Hybrid embryo research likely to be approved

Research using hybrid embryos is likely to be given the go-ahead this week
after warnings it would be a major blow to British science if the Government
watchdog refused to allow it.
 Researcher aim to create stem cells which can be manipulated in the
laboratory to mimic human cells
The Human Fertilisation and Embryology Authority (HFEA) will decide on
Wednesday whether to permit scientists to create human-animal hybrid embryos
to extract stem cells for research.
The studies could yield new treatments for diseases including Alzheimer's,
Parkinson's and motor neurone disease.
Early indications are that the HFEA will approve the concept in principle,
but it still has to decide on two specific applications from university
scientists - rulings which will come later this year.
Dr Stephen Minger, from King's College London, has applied to the HFEA to
create embryos using eggs taken from cows which have had their genetic
material removed and replaced with human cells.
The aim is to create stem cells which can be manipulated in the laboratory
to mimic human cells with genetic neurological diseases so potential
therapies can be developed.
The only other alternative, Dr Minger said, is to encourage thousands of
women to donate their eggs for research. "Ruling against this research would
be a real blow for science, not just stem cell research," he said.
"We thought that what we were doing was quite pragmatic. It is more
justified than trying to encourage thousands of young women to come forward
to undergo a fairly invasive procedure for research. In my opinion that is
not realistic and not justified."
Another application has been submitted by Dr Lyle Armstrong and his team at
Newcastle University to carry out basic research using stem cells taken from
hybrid embryos.
Hybrids have already been created in China and if the HFEA rules in favour
of the principle on Wednesday the two British applications will be put
before its licence committee in November.
A row erupted last year after a Government White Paper proposed banning the
technique following a backlash from a public consultation.
Scientists warned the consultation had been skewed by pro-life groups and so
the HFEA carried out its own.
In the meantime, the Government has published a draft Bill which would allow
hybrid embryos created using cloning techniques but not "true hybrids" where
a human egg is fertilised with animal sperm or vice versa.
The joint scrutiny committee said this should be removed and research
allowed on all hybrids.
Phil Willis, the Liberal Democrat MP for Harrogate and Knaresborough who is
chairman of the committee, said it was likely the final Bill will be amended
to reflect this before it went to MPs.
He said: "It would be fairly logical for the HFEA to go ahead and decide
these licences."
The Government's chief medical officer, Sir Liam Donaldson, is a
high-profile dissenter.
He has said that mixing human cells with animals cells should not be
permitted and it has been suggested that if the research is allowed he may
have to resign.
Mr Willis said: "Liam Donaldson has taken a very hard line on this. To have
the CMO talking about 'yuk' factors is not acceptable."
