British authorities have given the green light to controversial research involving implanting human DNA in animal cells. The aim is to create hybrid embryos from which stem cells can be extracted. Experts say such research is critical to unlocking treatments for genetic diseases.
Embryo Scientist Professor Lyle Armstrong said: “In one day we can easily get 200 cow eggs from a local slaughter house, the same applies to rabbits or perhaps pigs that we may be able to use. So it offers us a chance to make embryonic stem cell technology more accessible to everyone,”
But Britain’s Human Fertilization and Embryology Authority ruled that research projects should be considered on a case-by-case basis. That reflects ethical concerns by opponents who claim the procedure violates the rights of human embryos.
