This is a
most contentious topic. Into
the fray comes the latest research paper arguing that abortion
is indeed a risk fact for breast cancer. The work is entitled
‘The British Breast Cancer Epidemic: Trends, Patterns, Risk
Factors, and Forecasting’ and is authored by Patrick S.
Carroll, Jean S. Utshudiema and Julian Rodrigues. It was published in
the Journal of American Physicians and Surgeons (2017)
22: 8-15.
Can 70% of women be wrong?
Where Do They Stand? is a grass-roots, volunteer-led
initiative which exists to help the UK public to learn the
views of the general public and their elected representatives. Recently it
commissioned a ComRes poll to survey the public’s views prior
to the General Election on a variety of issues. In the poll of more
than 2,000 people, it found that 70% of women (and 60% of the
general population) wanted the abortion upper limit reduced
from 24 to 20 weeks and 60% wanted the limit set at 16 weeks. In addition, 90% of
those questioned wanted sex-selective abortions banned. The survey also
found that 90% thought a woman considering an abortion should
have a legal right to independent counselling from a source
that has no financial interest in her decision. Have you understood
those messages, General Election candidates?
Abortions by midwives?
Here is good news and bad news.
The good news is that more and more young doctors are
unwilling to perform abortions.
The bad news is that midwives might be given the task. At least, this is
the view expressed in an online paper by Sally Sheldon and
Joanne Fletcher (Journal of Family Planning &
Reproductive Health Care, 18 January 2017) and entitled
‘Vacuum aspiration for induced abortion could be safely and
legally performed by nurses and midwives.’
The
authors’ thesis is this: ‘Some 40% of abortions carried out in
England and Wales are done by vacuum aspiration. It is widely assumed
that, in order to be lawful, these procedures must be
performed by doctors. However,
a close reading of relevant law reveals that this assumption
is unfounded. On
the contrary, it would be lawful for appropriately trained
nurses or midwives, acting as part of a multidisciplinary
team, to carry out vacuum aspiration procedures. This interpretation
of the law offers the potential for developing more
streamlined, cost-effective abortion services, which would be
both safe and highly acceptable to patients.’
First, some
background. Sally
Sheldon, the lead author, is a Professor of law at the
University of Kent. For
more than 20 years she has campaigned for abortion-on-demand
and is currently a trustee of the British Pregnancy Advisory
Service (Bpas), the largest provider of abortions in the UK. Last year, she
received a government grant of £512,000 for a research project
called ‘The Abortion Act (1967): a Biography.’ This project was
begun in May 2016 and its findings will be launched at the
Houses of Parliament on 27 April 2018, the fiftieth
anniversary of the Abortion Act coming into force. In other words, Ms
Sheldon is hardly an impartial observer. This Sheldon and
Fletcher paper’s conclusions are therefore no surprise, but
they are still alarming.
They are
alarming because they recommend shifting the responsibility
for surgical abortions on to midwives and obstetric nurses. The vast majority of
these healthcare workers did not enter the profession to be
involved in terminating the lives of unborn babies –
anything but. Furthermore,
if implemented, this shift would probably prompt a further
erosion of freedom of conscience in the workplace and it would
create another no-go area for Christians and the 'morally
sensitive'.
Ellinor Grimmark
Ellinor Grimmark is a 40-year-old Swedish midwife and a
Christian who refuses to carry out abortions. She had originally
been offered employment at Höglandssjukhuset women's clinic in
Eksjö, southern Sweden, after completing an internship there
in 2013. She
gratefully accepted the job offer, but reminded them that she
could not perform abortions due to her strongly-held belief
that life begins at conception.
That was the deal-breaker. Her would-be boss,
the head of the maternity ward, called and left her a
voicemail saying that, ‘She was no longer welcome to work with
them’ and questioning ‘whether a person with [pro-life] views
actually can become a midwife.’
She filed a
civil rights complaint against the Höglandssjukhuset clinic
with the local Equality Ombudsman. When, in November
2015, the Ombudsman ruled that Grimmark had not been
discriminated against for her pro-life views, Grimmark
escalated the complaint by filing a suit in the Jönköping
district court with the help of a group called Scandinavian
Human Rights Lawyers. She
was seeking 80,000 Swedish kronas (£7,200) in compensation for
damages and 60,000 Swedish kronas (£5,400) in compensation for
discrimination. She
has consistently argued that her Christian beliefs make it
impossible for her to perform abortions and that it is also
unfair for the authorities to turn her down for nursing jobs
in the Jönköping region.
On 12 April
2017, a Swedish labour court of appeal defended the right of
the Jönköping region to require its midwives to carry out
abortions. Moreover,
the court maintained that she had not suffered discrimination,
that the authorities had not violated her ‘freedom of opinion
and expression’ and therefore it ruled against her.
The US
Alliance Defending Freedom (ADF) is a partner with her legal
team, the Scandinavian Human Rights Lawyers. An ADF lawyer,
Lorcan Price, explained, ‘What you have is a situation where
an otherwise qualified midwife, able and willing to offer all
the services a midwife traditionally offers in a hospital
cannot be involved in abortion, as she sees it as the taking
of human life. Rather
than attempting to accommodate her, to work around that one
objection, or working in any positive way, she was simply
sacked. She was
told flat out that until she agreed to be involved in the
performing of abortions she would not be employed in any
hospital in the Swedish health system.’
Ellinor
Grimmark’s supporters say that the judgement against her
contradicts international law protecting conscientious
objection. That,
they say, is the whole point of the European Convention on
Human Rights and the defence of conscientious objection is to
allow people to object to things they think of as
fundamentally wrong. She
now has a legal bill of about 1.5m kronas (£135,000). Ms Grimmark is
considering taking her case to a higher Swedish court, or even
to the European Court of Human Rights.
Decriminalising abortion – in England and
Wales
If you have read the previous item, you should not be
surprised by this piece.
On 12 March, Diana Johnson (Labour MP for Hull North)
tabled a Ten-Minute Rule Bill, entitled ‘Reproductive Health
(Access to Terminations) Bill 2016-2017’, which called for the
full decriminalisation of abortion across England and Wales. This would mean all
legal restrictions on abortion would be removed. It was part of a
campaign sponsored by Bpas, the Royal College of Midwives and
others to rip up sections 58 and 59 of the 1861 Offences
Against the Person Act, the 1967 Abortion Act and probably
also the 1929 Infant Life (Preservation) Act. Ten-minute rule
bills signal an issue in Parliament, but they very rarely are
given government time to allow them to be fully debated and
become law. The
1967 Abortion Act is a glaring exception to this pattern.
Opposition
to this Bill was led by Maria Caulfield (Conservative MP for
Lewes). During
her speech she stated, ‘I and many colleagues who share my
views will not be silenced as we seek to be a voice for the
voiceless … and as we argue for a more modern and humane
abortion law that not only upholds the dignity and rights of
women but the dignity and rights of the unborn child. A 21st-century
approach to this area must be based on a fuller and richer
understanding of human dignity and equality which doesn’t
treat women as a victim of her own body, which doesn’t treat
children as commodities, and which doesn’t treat marginalised
people such as young girls or children with Down’s Syndrome as
burdens or inconveniences.
On this count this Bill fails.’
MPs were
deeply divided on
the issue and the Bill was narrowly passed by 172 to 142. It was then read the
First time. The
Second Reading was set for 24 March, but then delayed until 12
May. In the
meantime, a General Election was called, Parliament was
dissolved and the Bill fell and no further action will be
taken. Hooray!
This vote
was won by the pro-abortionists.
OK, the Bill fell, but only because of unusual
circumstances. OK,
it was a Friday sitting and many MPs travel to their
constituencies on that day so attendance was poor. OK, ten-minute rule
bills seldom make progress.
But this episode should serve as a wake-up call to MPs
– there is real pressure at Westminster for a radical reform
of abortion law, the sort that would remove all legal
protection for the unborn.
Decriminalising abortion – in Australia
Decriminalisation is in the air, globally. Australia’s Northern
Territory Parliament decriminalised abortion on 21 March by a
margin of 20 to 4. The
reforms have legalised the use of abortion drugs, such as
RU-486, up to nine weeks into a pregnancy and repealed
legislation that made it illegal to provide an abortion or
supply a woman with abortion drugs. Also now permitted
are medical terminations in specialist clinics, instead of
solely in city hospitals.
Previously, women in remote areas travelled hundreds of
miles to access surgical abortions in urban hospitals.
Decriminalisation is indeed in the air, in the minds of some, in the plans of others, and already on the statute books of some jurisdictions. The alarm bells are ringing – they are a call to action. Have you heard them yet?
Assisted Reproductive Technologies
In vitro gametogenesis (IVG)
If
IVF is bioethically problematic, IVG is gruelling. Within the next 10
to 20 years, this new and controversial fertility technology,
called in vitro gametogenesis, could make it possible to
manipulate skin cells into creating a human baby. Though the
technology is difficult, the basic formula is simple, IVG =
iPSC + IVF. In
other words, take a skin, or any other adult, cell,
reprogramme it into an induced pluripotent stem cell (iPSC),
convert that into a gamete, that is, a sperm and/or an ovum,
use them in IVF to create a human embryo, transfer that into a
woman, and deliver a baby.
IVG is not
without its critics. As Professor Eli
Adashi of Brown University has declared,
‘There’s something troubling about an inexhaustible supply of
gametes that can be fertilized into an inexhaustible supply of
embryos.’ And,
for example, it also raises the spectre of ‘embryo farming’
and ‘designer babies’. It
would turn procreation into a transaction. It would introduce
further fractures into parenthood, allowing more human
combinations into the generation of a child. It would allow
singles, gays and lesbians to become parents. It would genetically
distance parents from child.
Contrariwise, it might allow one adult to be both
father and mother – the ultimate in inbreeding. And if gametes could
be generated from easily-collectable skin
cells, for example from a glass, people could be made parents
without their knowledge or consent. IVG has the
potential to rewrite the biology of human reproduction.
So
far,
the first phase of IVG, that is production of ova, or
oogenesis, has been successfully accomplished and tested by
Japanese researchers on mice, which produced healthy babies
derived from skin cells.
That work by Hikabe et al. was published
in Nature
(2016,
539: 299-303) as ‘Reconstitution in vitro of
the entire cycle of the mouse female germ line.’ The second phase of
IVG, in vitro
spermatogenesis from iPSC, has been variously reported, but
with methods that have proven difficult to replicate. And besides
biologically mice are not men.
Currently,
it is not feasible – technically or legally – to create a
human baby via IVG, but at least it is now plausible.
Another reason to shun IVF
A
document recently published (28 February 2017) by the ethics
committee of the American
Society for Reproductive Medicine (ASRM), entitled,
'Unconventional combinations of prospective parents:
ethical challenges faced by IVF providers', draws
attention to the potential dangers of ‘intrafamilial
reproductive arrangements.’
While so-called ‘collaborative reproduction’ typically
involves anonymous or unrelated individuals, such as family
friends, it is becoming increasingly common, at least in the
USA, for first-degree relatives to share ova, sperm or wombs.
The
document states that there are some combinations that should
be rejected outright because they are consanguineous, such as
the pairing of a sister’s ova with a brother’s sperm. There are also
‘incestuous unions’, such as a father providing sperm for a
daughter, who is using donated ova. On the other hand,
the committee is less opposed to arrangements such as a father
giving sperm to his son’s wife.
Such ‘intrafamilial arrangements’ raise concerns not
just about adverse genetic links but also about consent and
family dynamics.
Human embryos as trinkets
An
Australian company, Baby Bee Hummingbird, was launched in 2014
by midwife Amy McGlade. It
has pioneered a process to craft frozen human embryos into
jewellery. The
items cost between £50 and £350, depending on the piece, and
can be shipped worldwide.
Belinda and
Shaun Stafford, are happy customers. They used IVF to
conceive a son and a twin boy and girl. They did not know
what to do with the seven frozen ‘spare’ embryos they had left
over. Belinda
said, ‘Donating our embryos wasn’t an option for us and I
couldn’t justify the yearly storage fee. I’d heard others had
planted them in the garden, but we move a lot, so I couldn’t
do this.’ Instead,
they opted to have the embryos made into jewellery – in this
case, a heart-shaped pendant.
‘My embryos were my babies – frozen in time. When we completed
our family, it wasn’t in my heart to destroy them. Now they are forever
with me in a beautiful keepsake.’
The company
has faced a huge backlash on social media for making human
embryos into commodities.
The answer is not to justify this business, but to stay
away from IVF in the first place and avoid the problem of
those inevitable supernumerary embryos.
The ova donation racket
In early May, The
Daily Mail published a front-page story about the
ethical and exploitative nature of ‘egg donation’. The paper’s major
allegation against the fertility industry, as visited by its
undercover journalists, was that women are being persuaded to
donate their healthy ova in return for free or discounted IVF
treatments, specifcally at several clinics in London,
Hertfordshire and County Durham.
The exposé
has
cajoled the HFEA into investigating the paper’s claims. And Health
Secretary, Jeremy Hunt, has said the allegations are ‘serious
and worrying’.
Human ova are rare, but also at a financial premium. They are needed for
IVF and embryo research.
The voluntary donation of ova is regarded as an important
safeguard which reduces the extent to which a woman’s body can
be commodified. Thus
buying and selling of human ova is generally regarded as
unethical. The
fertility pioneer, Lord Robert Winston, responded to the The Daily
Mail's evidence of this practice as, 'I
fear that some in my profession have no moral or ethical
compass. These women cannot appreciate the
consequences of what they’re agreeing to. These patients are
vulnerable and anxious and likely to be worried about money. The women who are
egg sharing are under duress and that’s really worrying.’
There are considerable health risks to multiple ova
production and donation.
It is invasive and often painful. The inevitable
process of superovulation can lead to ovarian hyperstimulation
syndrome (OHSS), which is hazardous. Follow-up of these
women is random. Psychological
harm is not uncommon. It
is frequently disadvantaged and economically-needy women who
are targeted. For
example, Newcastle University has advertised that ‘Donors will
receive £500 compensation for a completed donation
cycle.’ Is the health of women unimportant? Does research and IVF
trump their well-being? Have
fertility practitioners lost or fogotten their principles,
morals and guidelines? Who
will protect these women?
Where are the regulators?
On 2 May, the HFEA issued the following statement, ‘We have
clear rules in our code of practice, enforced by inspectors,
that clinics must explain the risks and chance of success of
treatment to each patient and donor, and avoid encouraging
people to donate eggs and sperm with the promise of financial
gain. This
investigation highlights potential breaches of our code and
our inspectors will be investigating each allegation presented
to us. If we find
that a clinic is in breach of our code, we will take
regulatory action.’ Oh yes? Come on paper tiger,
show us some teeth.
‘Three-parent’ IVF – the details
In April, John Zhang and his team, who created the world’s first
‘three-parent’ IVF baby, published more details about the
techniques used in the child’s conception (Zhang, J. et al. (2017) Reproductive BioMedicine
Online 34:
361–368). The
essential procedure was already known. It involved removing
the nucleus from a healthy donor ovum and replacing it with a
nucleus taken from the ovum of the woman who carried the
neurological disease, Leigh syndrome. This leaves the
donor’s healthy mitochondria intact. The scientists then
performed IVF by fertilising the modified ovum with the father’s
sperm before transferring it into the mother’s uterus. The resulting baby boy
was born in April 2016.
Zhang’s
new
paper reports the more detailed methods used to transfer the
mitochondria and how they froze and heated the embryo before
using an electrical pulse to fuse the mother's nucleus into
the donor ovum. It
also reveals that some diseased DNA from the mother was
carried over inadvertently into the donor ovum.
But the big
questions remain – will the child's health be affected by the
procedures and/or by the traces of the mother's diseased
mitochondrial DNA that he carries, and will his mitochondria
function properly? The
percentage of affected mitochondria varies among his tissues. Just 2% of the
mitochondrial DNA of cells in the boy’s urine came from the
mother, but it was as high as 9% in cells from his circumcised
foreskin.
But none of these key questions are likely to be answered because his parents have refused any further mitochondrial testing on the baby unless there is a medical need. It is not clear whether the family was ever asked to consent to long-term medical monitoring. There is now no way to assess the long-term health of this uniquely-conceived child and determine if ‘three-parent’ IVF is indeed safe. What are the risks of this experimental technique of mitochondrial replacement therapy? What is in the best interests of the boy? This is medical science at its worst. This is all most unsatisfactory.
'Three-parent' IVF – the approvalOn the basis of the work of Zhang
and his colleagues, as reported above, there are more
questions than answers concerning ‘three-parent’
IVF, or mitochondrial donation.
Has the HFEA, again in its usual overenthusiasm to be
at the forefront of world-beating research, jumped the gun?
New embryo experimentation guidelines
There
is
pressure building to extend the 1990 Human Fertilisation and
Embryology Act's 14-day
rule for embryo experimentation.
Now new regulations are being proposed based on a quite
different concept. They
were published on 21 March 2017 in eLife under the title
of ‘Addressing the ethical issues raised by synthetic human
entities with embryo-like features’ by Aarh, J. et al. from the
Department of Genetics, Harvard Medical School.
The 14-day rule,
based on the appearance of the primitive streak, was always a
daft and arbitrary cut-off point.
Now, because scientists have the ability to culture human
embryos beyond 14 days and because they can create ‘synthetic'
structures, such as organoids or embryos assembled from stem
cells in the laboratory, new rules are required, we are told. These biological
structures, referred to in the eLife paper as
'synthetic human entities with embryo-like features' (SHEEFs),
are becoming increasingly sophisticated, and even more complex
examples could soon be constructed, such as, a rudimentary brain
connected to a beating heart.
Limits, such as
the current 14-day rule, are based on 'stop signs', or the
appearance of certain features.
These, Aarh and colleagues argue, are unsuitable for
SHEEF research. This
is because SHEEFs do not necessarily follow the same
developmental processes as ‘normal’ embryos and would not
necessarily hit such ‘stop sign’ limits before developing
attributes that are of bioethical concern. Instead of ‘stop
signs’ they propose ‘perimeter fences’, where there is an
agreement that there is an area of concern. For example, it might
be agreed that we cannot make a brain that will allow it to feel
pain, or we cannot make something like a heart, but we can make
up to it … as long as it doesn't start beating.’
This is all
scientific hocus-pocus. How
could
there ever be universal agreement on such issues? What would be the
objective, as opposed to the subjective, criterion for instance
with the heartbeat scenario?
For a start, what is so special about a beating heart? Is not that merely an
emotive ‘perimeter fence’?
And, when does it start beating? Day 21 or day 22 of
'normal' development? This
is sentimental, arbitrary claptrap. It is no better than
the 14-day rule. It
would be a replacement scheme that is just as broken as the
original.
Who can doubt
that the 14-day rule will be extended? As Melanie
McDonagh, writing in The
Spectator (4 March 2017), put it, ‘In Britain you can
pretty well get away with anything if you say it’s to help sick
kiddies or help infertile couples become pregnant. At what point you say
that experimenting on early human lives for the benefit of
others is anyone’s guess. In
pragmatic, post-Protestant Britain, the end justifies the
means.'
IVF –
a profitable business
According to an industrial analysis company, Research
and Markets, the world market for IVF and IVF products
will grow from US$8.4 billion this year to $12.5 billion by
2022. Research and Markets
says that, ‘Factors driving growth in the market are
increasing number of cases of infertility owing to lifestyle
changes involving unhealthy nutritional habits, penetration of
advanced procedures in developing nations, and favorable
government initiatives. Geographically,
Asia-Pacific is expected to witness the highest growth owing
to rising aging population in Japan, favorable childbearing
policies in China and rising awareness in countries like
India, South Korea, and Thailand.'
Demand for
IVF is growing at about 10% annually, owing to raising
awareness and social acceptability. Infertility is no
longer just a Western problem, with about 25% of couples in
developing countries affected by it, according to the World
Health Organisation.
I've always
maintained that the two greatest drivers of almost every
corrupt human enterprise are sex and money – see what I mean?
In April
2015, it was reported that researchers in China, led by Junjiu
Huang at the Sun Yat-sen University in Guangzhou, used the
gene-editing tool CRISPR-Cas9 to edit the rogue gene responsible
for the disease β-thalassaemia out of human embryos. The embryos were
non-viable because they carried extra chromosomes. These world-first
results were published in the online journal Protein & Cell
under the title, ‘CRISPR/Cas9-mediated gene editing in human
tripronuclear zygotes.’ The
world-second report of editing human embryos appeared in the
April 2016 edition of the Journal
of Assisted Reproduction and Genetics by Yong Fan and
colleagues from the Guangzhou Medical University. Their paper was
entitled, ‘Introducing precise genetic modifications into human
3PN embryos by CRISPR/Cas-mediated genome editing.’ They introduced a
mutated gene, known as CCR5Δ32, into some of the embryos, which
can confer resistance to HIV.
Again, the embryos they used, ‘spares’ from IVF, were
reported to be abnormal and unsuitable for implantation because
they also contained an extra set of chromosomes – they were
destroyed three days after the experiment began.
So the next
tantalising challenge was to try gene editing using viable human
embryos. In June
2017, a report in Molecular
Genetics and Genomics, entitled ‘CRISPR/Cas9-mediated
gene editing in human zygotes using Cas9 protein’ by Tang et al. showed, for
the first time that mutations in normal human embryos could
indeed be corrected. The
team, led by Jianqiao Liu at the Third Affiliated Hospital of
Guangzhou Medical University, used ova leftover from IVF
procedures and fertilised them with donor sperm from two men who
suffered from diseases that are common in China. Six embryos were
created. One of the
sperm donors had a mutation called β41-42, which causes
β-thalassemia, while the other donor had a mutation in the G6PD
gene, which is a cause of favism, a disorder which results
in the spontaneous destruction of red blood cells after
eating, for example, broad beans.
Four of the
resulting embryos had the β41-42 mutation, while two had
mutations in the G6PD gene. They were subjected to
the CRISPR-Cas technique and allowed to develop for two days. Then their DNA was
analysed to establish if the mutations had been successfully
corrected. The
β41-42 mutation was only partially corrected in one embryo,
forming a mosaic embryo. CRISPR-Cas
induced an additional mutation in another embryo, and the
technique did not work at all in the two remaining embryos. The mutation in the G6PD
gene was successfully repaired in one embryo. In the other embryo,
it was corrected only in some cells, thus also forming a mosaic
embryo, that is, with a mixture of edited and unedited cells, a
combination of both repaired and unrepaired cells.
This
work has been described as ‘promising’ and ‘encouraging’ yet
it pointed out serious limitations and complications. The trial was small, the methodology
not entirely efficient and it included the continuing worry of
‘off-target’ mutations. The
occurrence of mosaicism also needs solving – perhaps by editing
ova and sperm, rather than embryos. And, of course, there
are all those underlying grave bioethical concerns about
genetically editing humans.
In fact, this type of germline
editing probably will not be the first way CRISPR-Cas9 is used
to tackle human genetic diseases. Researchers are
already planning experiments to edit genes in the
somatic cells of patients.
Such experiments come with fewer bioethical questions,
but also many remaining technical hurdles. And anyway, almost all inherited diseases can
already be prevented for most couples by existing forms of
screening, such as preimplantation genetic diagnosis (PGD) of
IVF embryos, without any need for CRISPR.
CRISPR,
drugs and tumours
Tumours can often become
resistant to individual drugs, but it is well known that
certain drug combinations can be surprisingly effective in
destroying such drug-resistant tumours. Michael Bassik and
his colleagues at Stanford University have developed a method
based on CRISPR–Cas9 that can offer a way to discover such
useful mixtures. The
work was reported in Nature
(23 March 2017, 543:
467) under the title, ‘CRISPR finds drug synergy.’
Their method
systematically disables two genes at a time in cells. They used their system
to knock out 21,321 pairs of potential drug targets in leukaemia
cells, looking for combinations that work synergistically to
kill cancer cells. They
found that disabling two genes, called BCL2L1 and MCL1,
destroyed drug-resistant cells. Drugs
that inhibited these genes killed more leukaemia cells than each
of the two medicines did when used individually. It looks like a step
forward in cancer treatment.
Who owns CRISPR?
Where would biology be without an input from lawyers? For ages, a
hotly-contested battle has been raging between the Broad
Institute of MIT and the University of California over who
owns the intellectual-property rights to CRISPR, the
potentially lucrative technology. Although the Broad
Institute was awarded its patents first, the University of
California was the first to apply for a patent on the
technology. The
Californian scientists also argue that its team in Berkeley
invented the technique before investigators at the Broad.
In December 2016, the US Patent and Trademark Office
(USPTO) upheld a series of patents granted to the Broad
Institute. Then
lawyers representing the University of California filed for an
‘interference proceeding’ in order to have the Broad’s patents
rejected. But on
15 February 2017, patent judges determined that there was no
interference, meaning that the Broad Institute’s patents will
stand. The
University of California’s patent application will now be
referred back to an examiner, but legal challenges will
probably continue – of course!
Biology and law – what a potent cauldron of
contrary disciplines.
Stem-Cell
Technologies
In May
2017, the Wellcome Trust and the Medical Research Council
(MRC) announced a £12.75 million initiative to create a
catalogue of high-quality adult stem cells, the so-called
induced pluripotent stem (iPS) cells. This initiative
known as HipSci is the UK’s largest resource of human stem
cells and has been heralded as a powerful research tool for
studying human development and diseases including cancer,
Alzheimer’s and heart disease.
The
strategy is to lay the foundations to create a new iPS cell
bank, providing a world-class resource for UK researchers. So far, 711 cell
lines have been created and detailed information about their
genomes, the proteins they express and their cell biology has
been generated. This
knowledge base is openly available to the research community.
It is
significant that this Initiative deals exclusively with iPS
cells, produced by that Nobel Prize-winning technology, which
is bioethically uncontroversial, and not the once-celebrated
embryonic stem cells, which are bioethically objectionable.
The Californian experience
In 2004, Californian voters approved $3 billion funding for
stem-cell research. Biologists
flocked to the Golden State and citizens dreamed of cures for
Parkinson’s disease, spinal-cord injuries and so on. Now, that
pot of money is running dry and treatments have yet to emerge. Will Californians
pour billions more into stem-cell research controlled by the
California Institute for Regenerative Medicine (CIRM)? If not, hundreds of
scientists could be without jobs and potentially promising
therapies could be abandoned before they reach the clinic.
Already
CIRM has had its fingers badly burned – it initially invested
heavily in embryonic stem-cell research that got virtually
nowhere. It then,
too late, switched to adult stem and iPS cell research. Now the CIRM is
doling out its final $650 million while its leaders are
seeking money from the private sector to carry projects beyond
2020, when the money will finally run out.
There are never enough transplant organs to meet demand. Could stem cells be
used to create additional organs? In 2010, a team led
by University of Tokyo Professor Hiromitsu Nakauchi devised a
new technique for creating such organs using iPS cells. The team injected a
rat iPS cell into an embryo grown from a mouse’s fertilised
egg, which was then put back into the mouse’s womb, which
resulted in a functional rat pancreas in a newborn mouse. Could such
technology create human organs inside the bodies of animals,
such as pigs?
In January
2017, scientists at the Salk Institute for Biological Studies
in the US announced that they had inserted human iPS cells
into pig embryos and successfully created pig foetuses
containing human cells. The
Institute said this achievement marked, ‘the first step toward
the generation of transplantable human organs using large
animals.’ The
work was reported in Cell (168: 473-486) under
the title, ‘Interspecies Chimerism with Mammalian Pluripotent
Stem Cells.’
In the same
month, the University of Tokyo team announced that it had
created a pancreas derived from a mouse in a rat’s body. The implanted mouse
remained in good health for a long period of time, with
minimal doses of immune suppressor drugs required. Nakauchi stated, ‘We
proved our method to be effective and safe. We’re planning to
start producing human organs within five years, and hope to
deliver them to patients.’
However, for ethical reasons putting an embryo
containing human cells into an animal womb is prohibited in
Japan. Nakauchi
is therefore planning to move his base to a US laboratory to
create human-sheep chimeras.
‘Artificial embryos’ from stem cells
Scientists at the University of Cambridge have used two types
of stem cells from mice and a 3-D scaffold to create
‘artificial embryos’, structures that closely resemble natural
mouse embryos. Previous
work had limited success, but this is believed to be a world
first, with the hope of improving fertility treatments (of
course) as well as insights into early embryo development (of
course).
This work,
published in the journal Science (2 March 2017) as
‘Assembly of embryonic and extra-embryonic stem cells to mimic
embryogenesis in vitro’, used embryonic-stem cells plus a
second type of stem cell, known as extra-embryonic trophoblast
stem cells, which form the placenta. Lead researcher,
Magdalena Zernicka Goetz said, ‘We knew that interactions
between the different types of stem cells are important for
development, but the striking thing that our new work
illustrates is that this is a real partnership – these cells
truly guide each other.’
Christians will recall Psalm 139: 14, ‘I praise you
because I am fearfully and wonderfully made.’ However, an
artificial embryo is unlikely to develop into a healthy foetus
as it would probably need the third form of stem cell, which
develops into the yolk sac that provides nutrition. And, of course, if
such experimental human embryos were created, they would not
be allowed to develop beyond 14 days. So, it is obvious
that bioethical predicaments are stacking up against this
technique.
Blood from stem cells
Could this be the end of the road for all those altruistic
blood donors? Over
the last twenty or so years scientists have longed to produce
‘artificial blood’. Now
that goal is apparently within grasp. The breakthrough has
centred on a special sort of stem cell known as the
haematopoietic stem cell (HSC).
From this type of cell all the basic components of
blood are generated. And
a group, led by George Daley at Harvard University, has
seemingly overcome the final technical hurdles. They first took
ordinary human adult cells, added a mixture of seven
transcription factors which reprogrammed them into induced
pluripotent stem cells (iPSC) and then coaxed these into HSCs. The end-product,
when injected into mice, produced the complete set of human
blood cells – well, almost, though not exactly identical to
those found in nature, they were tantalisingly close.
The outlook
could be staggeringly good.
For instance, take cells from patients with genetic
blood disorders including leukaemia, use CRISPR to correct the
genetic defect and then make functional blood cells so that
patients could receive laboratory-grown versions of their own
healthy cells. Also, use
cells from universal donors and make limitless supplies of
donative blood for everyone.
We are not there yet – human clinical trials are needed
and safety concerns must be allayed, but it certainly does
look promising. This
work was reported in Nature (online 17 May 2017) under
the title, ‘Haematopoietic stem and progenitor cells from
human pluripotent stem cells.’
Oesophagi from stem cells
Doctors at Great Ormond Street Hospital (GOSH) are set to
become the first in the world to modify pig organs to treat
newborn babies with birth defects. Next year, about 10
babies born with a section of their oesophagi missing, a
condition known as oesophageal atresia, are to receive
transplants harvested from pigs and then modified using the
child’s stem cells. The
condition can be diagnosed in the foetus at around 20 weeks. Oesophagi of varying
sizes have already been taken from pigs at a British farm in
readiness. These
‘animal scaffolds’ will have all their porcine cells removed
and then for the next 8 weeks will be reengineered with the
born child’s stem cells taken soon after birth from the baby’s
muscle and residual oesophagus.
About 2 to 3 months after birth, the ‘new’ oesophagus
will be transplanted.
The man
behind this novel treatment is Professor Paolo De Coppi, a
consultant paediatric surgeon at GOSH. In 2010, he
pioneered a similarly ground-breaking transplant in which a
13-year-old boy was given a new trachea, which had been
created from a deceased human donor plus the teenager’s stem
cells.
Age-related macular degeneration
(AMD) and iPS cells
In 2014, Masayo Takahashi and Yasuo Kurimoto from the RIKEN
Center for Developmental Biology in Kobe took retinal cells
derived from induced pluripotent stem (iPS) cells and
successfully transplanted them into a woman suffering from
age-related macular degeneration (AMD). This was the world’s
first surgical procedure using iPS cells.
On 28 March
2017, the same Japanese scientists undertook a similar
procedure, but with an important twist. This time, a
Japanese man in his 60s became the first person to receive a
retinal repair with cells derived from iPS cells donated by an
anonymous donor. Skin
cells from the donor were reprogrammed into iPS cells and then
turned into a type of retinal cell, which was in turn
transplanted onto the retina of the AMD patient. The success of the
surgery will have to wait while the fate and function of the
introduced cells are monitored.
The work was reported in The New England Journal of
Medicine (2017, 376: 1038-1046) as ‘Autologous
Induced Stem-Cell-Derived Retinal Cells for Macular
Degeneration.’
And when it all goes wrong
It has been reported (The New England Journal of Medicine
2017, 376: 1047-1053) that three patients have
developed vision loss in both eyes after undergoing stem-cell
injections for age-related macular degeneration (AMD) at a US
clinic. The
authors have called for stricter management of both the
procedures using stem cells and the clinics providing these
treatments. They
highlighted the need to increase public awareness of the
‘possibility of devastating outcomes’ with such unregulated
treatments. In
this case, adipose tissue-derived ‘stem cells’ had been used
and all three patients experienced severe visual loss after
one year. This is
beyond sad. Beware, not all stem-cell ‘treatments’ are
panaceas. Stem-cell
charlatans are out there.
Euthanasia and Assisted Suicide
Noel Conway – the latest
Noel Conway is the 67-year-old retired college lecturer, who has
motor neurone disease (MND), and is not expected to live for
more than 12 months. Mr
Conway wants the right to die.
He wants a declaration that the 1961 Suicide Act is
incompatible with Article 8 of the 1998 Human Rights Act, which
relates to respect for private and family life, and Article 14,
which protects from discrimination.

months or less to live;

Euthanasia in Québec
The report on the first full year (2016), since Québec legalised
euthanasia has been published.
It is alarming – compared with the first six months of
2016, the rate during the last half of the year had almost
doubled. According
to the Protection of Conscience Project report, ‘If Québec's
rate continues without escalation throughout 2017, it will
exceed that achieved by Belgium after nine years.’
CBC News has reported that 1,324 medically-assisted deaths
occurred in Canada during the 10 months since legalisation on 17
June 2016. The
actual number is likely to be higher, as some provinces, notably
Québec, British Columbia and New Brunswick, were unable to
provide up-to-date information, though Québec jumped the gun
with legalisation beginning on 10 December 2015.
The Netherlands
recently reported that there were 6,091 assisted suicides in
2016, representing a 10% increase on the previous year and 4% of
all deaths. Based
on the current number of assisted deaths, it is possible that
Canada will surpass both the Netherlands and Belgium.
In mid-February, Washington, DC became the seventh jurisdiction
in the US to legalise assisted suicide, as the
Republican-controlled Congress failed to block the law. The other members of
the infamous US septet are California, Colorado, Oregon,
Vermont, Washington state and Montana.
Just what is happening in Montana?
The status of assisted suicide in Montana is curiously
unsettled. In 2009,
the Montana Supreme Court decided that, ‘a terminally-ill
patient’s consent to physician-assisted aid in dying constitutes
a statutory defense to a charge of homicide against the aiding
physician.’ In
other words, there is nothing in Montana's state’s law that
prohibits a doctor from helping a patient to commit suicide. This effectively
permitted assisted suicide – without input from the Montana
legislature.
For almost the
last two decades, opponents and supporters of assisted suicide
have regularly tried to introduce bills to settle the matter,
that is, either to regulate or to ban assisted suicide. So far, none of them has
succeeded. The
latest banning bill, House Bill 365, almost succeeded, but then
failed at the very last minute.
The Bill, which declared that a patient’s consent would
not be a defense for an assisting doctor, passed a second
reading on a 52 to 48 vote during 28 February. But at the third reading
on the next day, 1 March, the Bill was defeated.
So what
happened? It was a
classic case of legislative comedy. On 1 March, two
lawmakers changed their vote to support assisted suicide, making
that day’s vote 50 to 50. Then
one decided not to support the Bill, making it 51 for and 49
against. Meanwhile
another member of the House, Peggy Webb, a Republican who
opposes assisted suicide, made a blunder and voted for the Bill,
making the outcome 50 to 50.
‘It was a mistake,’ said Ms Webb, but it was too late to
change it back.’ The
sponsor of the Bill, Brad Tschida, was philosophical about his
colleague’s error. ‘No
snowflake in an avalanche feels guilty’, he said. ‘Human beings are
emotional creatures more than they are rational.’
The traffic is not all one way
The world, including the USA, has not gone assisted-suicide mad. Despite that
impression from the media, several anti-life bills have been
recently defeated in Indiana, Mississippi, Tennessee and New
Mexico. For
example, in New Mexico, the state Senate voted 22 to 20 against
a bill to legalise assisted suicide for people expected to die
within six months. Similar
bills have stalled in Hawaii, Maryland, Utah and Wyoming.
For instance, in
sunny Hawaii, a House of Representatives committee unanimously
decided recently not to advance a proposed Medical Aid in Dying
Act allowing physicians to prescribe lethal drugs on the same
day a patient is diagnosed as terminally ill. Furthermore, the
Hawaii legislature passed not one of the five assisted-suicide
bills proposed during its 2016 session – all failed by the May 4
deadline adjournment.
Meanwhile, Maine has also bucked the apparent trend and defeated an assisted-suicide bill. On 18 May, the Maine State Senate narrowly passed a measure called An Act to Support Death with Dignity by 16 to 15. But on 23 May, the Maine House of Representatives voted 85 to 61 against it. This was the eighth attempt in recent years by Maine activists to change a lethal dose of drugs into a ‘medical treatment’.
Also, at the end of May, the Tasmanian Parliament rejected the latest attempt to legalise euthanasia in the Australian state. Although the media forecast that the vote would be close, The Voluntary Assisted Dying Bill 2016 was defeated in the lower house by 16-8. This was the third try in 10 years to pass a euthanasia bill. As one opponent of the Bill declared, ‘No one can say that the Tasmanian Parliament has not taken this issue seriously. This is a resounding affirmation that Tasmanian society takes a dim view of doctors helping people to suicide. Other Australian states should take note.’
USA and Elsewhere
This is not the place to provide a comprehensive assessment of
President Trump’s first few months in the White House. Suffice to say he
has made some sweeping, and positive, policy changes in terms
of bioethical issues. For
example, as recently as 15 May, he expanded the Mexico City
Policy, which bans federal funding for abortions outside US
borders. And his
so-called Protecting Life in Global Health Assistance policy
also blocks US funding of foreign aid to non-governmental
organisations that provide or promote abortion or mention
abortion in connection with family planning. The policy applies
to approximately $8.8 billion of aid.
Furthermore, he
has raised the profile of this year’s annual National March for
Life. He has signed
an executive order entitled ‘Promoting Free Speech and Religious
Liberty’. He has
chosen the evidently pro-life Neil Gorsuch for the key role of a
US Supreme Court Justice and has also made other strong pro-life
appointments including the choice of his vice-president, Mike
Pence; Attorney General, Jeff Sessions; Health and Human
Services Secretary, Tom Price, and Counselor to the President,
Kellyanne Conway. Most
recently the pro-life activist Charmaine Yoest has been given
the job of Assistant Secretary of Public Affairs at the
Department of Health and Human Services (HHS). Yoest is the former
CEO of Americans United for Life and regarded as the ‘legal
architect of the pro-life movement’. The man Yoest is
replacing is now a vice-president of Planned Parenthood. And Trump has recently
hired another top social conservative, Shannon Royce, former
chief of staff at the pro-life lobbying organisation, the Family
Research Council, to work in the HHS as the Director of the
Center for Faith-based and Neighborhood Partnerships. And so the impressive
recruiting list goes on.
And to top it
all, Planned Parenthood, the largest abortion provider in the
US, is about to be defunded to the tune of an annual $450
million. At least,
President Trump's 2018 budget proposal would withhold all
federal funds from Planned Parenthood, if, and it may be a big
‘if’, the new Republican healthcare legislation, the so-called
American Health Care Act (AHCA), which was narrowly approved by
the House of Representatives (217 to 213) in early May, also
passes the Senate and is signed into law. It would mean that Trump
has kept his pro-life promises, including stopping US taxpayers
from being forced to fund abortion and abortion businesses. Of course, there have
been disappointments, but there is no denying that the President
is packing his administration with pro-life, pro-family
advocates.
Abortion and climate change
You have probably never linked these two topics. Well, that old US
radical feminist icon from the 1960, Gloria Steinem, has. She, who has long
campaigned for unrestricted, government-funded abortion and she,
who popularised the ‘I got an abortion’ t-shirt, has found a new
string to her bow. She is now blaming ‘man-made’ climate change
on too few women aborting their children.
In a 9 May
interview with Refinery29, the American-based fashion,
style, and beauty website, she said, ‘What causes climate
deprivation is population.’
And, ‘If we had not been systematically forcing women to
have children they don’t want or can’t care for over the 500
years of patriarchy, we wouldn’t have the climate problems that
we have. That’s the
fundamental cause of climate change.’ And, ‘The world’s main
salvation from polar ice-cap melt is more abortions.’ The 83-year-old former
Playboy bunny is now officially batty.
Abortion law in Iowa and other US states
On 18 April, the Iowa legislature passed a bill banning most
abortions after 20 weeks with no exceptions for rape, incest or
foetal anomalies, though it does permit abortions in cases when
a mother’s life or health is at risk. The state Senate voted
30 to 20 to approve the so-called Senate File 471 after heated
debate. The law
would include a 72-hour waiting period prior to abortion. On 5 May, the bill was
signed into law by Governor Terry Branstad.
This legislation
makes Iowa the sixth US state to have a three-day ‘cooling-off’
wait before an abortion. Sixteen
other states have banned abortion after 20 weeks, namely,
Alabama, Arkansas, Georgia, Idaho, Kansas, Kentucky, Louisiana,
Nebraska, North Dakota, Ohio, Oklahoma, South Carolina, South
Dakota, Texas, West Virginia and Wisconsin. When those two great
seaboard states of California and New York are included in this
list we will know that serious pro-life legislation is being
enacted in the USA.
Abortion in New South Wales
In May, the Upper House of the New South Wales parliament was
brought to a shocked silence as one of the largest official
parliamentary petitions in its history was tabled by the Hon.
Greg Donnelly. The
petition contained 56,559 signatures. Members looked away
from their phones and paid attention as two of Donnelly’s staff
members brought in large document boxes containing the petition
sheets. An audible
gasp filled the chamber.
The petition
opposed the Abortion Law Reform (Miscellaneous Acts Amendment)
Bill 2016. That
Bill aimed to decriminalise abortion, specifically to ‘… amend
certain Acts to repeal offences relating to abortion, to specify
a ground of unsatisfactory professional conduct by a medical
practitioner with respect to abortion and to establish exclusion
zones in order to prohibit certain behaviour near premises at
which abortions are provided.’
This opposing petition contained the signatures of
residents from Sydney and throughout regional areas of New South
Wales. The petition
coordinator, Rebecca Gosper from Youth for Life, said, ‘We were
really hoping to get 10,000.’
She simply recruited a few friends, created a page on
Facebook for the campaign, and off it took.
The author of
the Bill, Mehreen Faruqi, was not present when the pro-life
petition was tabled. She
has her own official petition in favour of the Bill, running
since November 2015, which is yet to be presented to the
Parliament. An
unofficial supporting online petition contained just 2,028
signatures. On
Thursday 11 May, the Bill was roundly defeated –
Ayes 14 and Noes 25.
Bad news for France
On Sunday 14 May, the 39-year-old Emmanuel Macron took over as
France’s new president. His
predecessor,
François Hollande, was a pro-life, pro-family disaster. He extended abortion
rights, legalised gay ‘marriage’, permitted terminal sedation,
and so on. Will Macron be any better? Probably not. His electoral platform
certainly did not propose a single pro-life or pro-family
measure.
It seems as
though the traditional French secular state with its entrenched
Enlightenment philosophy is set to continue. Perhaps the most that
its minority of pro-life citizens can hope for is a preservation
of the status quo and an avoidance of any further sliding into
the culture of death.
Ireland and abortion
Over a weekend in late April, The Citizens' Assembly voted on a
series of questions about the Eighth Amendment of the Irish
Constitution. This
protects the equal right to life of the mother and unborn child. The Assembly, which
consisted of 99 people randomly selected by a polling company
and chaired by a Supreme Court judge, Ms. Justice Mary Laffoy,
recommended that Ireland approve the legalisation of abortion.
Almost
two-thirds (64%) of the Assembly voted for decriminalisation of
abortion, with almost half (48%) recommending an unrestricted
right to abortion in the first three months of pregnancy, and
44% saying this should be extended to 22 weeks. Some (8%) thought there should
be no restrictions on gestational age.
The results of
these votes will be submitted to the Dáil sometime in June and
will initially be considered by a 20-member Oireachtas Committee
which will decide whether legislative changes should be put to
the two houses of the Irish Parliament, the Oireachtas, namely
the Dáil and the Seanad. It
is considered likely that a new referendum on the Eighth
Amendment will be called, probably early next year.
