Two new techniques have been developed by fertility scientists which
would allow women using donated eggs for in vitro fertilisation to pass
on most of their own genes. Both techniques involve the removal of the
donor egg's nucleus, and then either the mother's chromosomes are
injected into the egg, or the mother's egg is 'glued' to the donor egg
and the pair of eggs are then induced to fuse. The father's sperm is
also introduced for fertilisation. The French, Italian and Spanish
scientists on the team claim that their research will aid the
development of so-called therapeutic cloning of embryos to produce body
parts, but insist that the experiments are not aimed at human
reproductive cloning. Even though the nucleus of the donor egg will be
removed, some of the donor's genetic material will remain in the
mitochondria. This has prompted Nuala Scarisbrick, of anti-abortion
charity Life, to describe the fact that a child would end up with the
genes of two women as "utterly repugnant to anyone who has a
traditional view of the creation of life." [The Daily Telegraph, Daily
Mail & Metro, 27th April]
The Science Editor of The Guardian newspaper in Britain has concluded
that stem cell therapy will go ahead and that the use of five or
six-day-old embryos will become increasingly necessary. He writes,
"Just as there are not enough donor hearts to meet demand for
transplant surgery, so there will not be enough donated embryos to meet
the demand for therapeutic cloning." [The Guardian, 27th April]
The US Senate health appropriations subcommittee has been considering
stem cell research. Superman actor Christopher Reeve addressed the
committee yesterday arguing that it is unethical for donated unused
embryos "that will never become human beings" to be thrown away when
they could help save thousands of lives. However, Senator Sam Brownback
disputed this argument and compared embryo destruction for science to
Nazi experiments on Jews which followed the rationale "these people are
going to be killed, why not experiment on them?". Furthermore, research
on embryos was branded unnecessary because some stem cells do roam
inside adults' bodies and could be used as an alternative. [Associated
