Human-Animal Hybrid Embryo Research Goes Forward

The government has overturned its proposed ban on the creation of human-animal embryos and now wants to allow them to be used to develop new treatments for incurable diseases such as Parkinson's and Alzheimer's.

The proposal, in a new draft fertility bill published today, would allow scientists to create three different types of hybrid embryos.

Scientists would be allowed to grow the embryos in a lab for no more than two weeks, and it would be illegal to implant them in a human.

...a cytoplasmic hybrid, is created by transferring the nuclei of human cells, such as skin cells, into animal eggs from which almost all the genetic material has been removed.

This is this type of human-animal embryo that is being developed in British universities. Scientists say that developing these embryos will provide a plentiful source of stem cells...


What have we become?
