Biology Mix Up
“Most support was expressed for the creation of so-called cytoplasmic hybrid embryos, in which a human cell is inserted into an empty animal egg. Other hybrid embryos, such as those created by fertilising an animal egg with human sperm, or vice versa, were less well supported.
In December, the government sparked a revolt by scientists, patient groups and medical researchers when it published a white paper containing proposals to outlaw almost all research into animal-human embryos. The research has since been backed by Nobel prizewinners, the Medical Research Council, the Wellcome Trust, the Commons science and technology committee, and the government's chief science adviser, Sir David King.
In May, the government withdrew its opposition in a draft fertility bill and now seeks to outlaw only embryos created by mixing sperm and eggs from humans and animals. The bill will be put before parliament before the end of the year.”
