UK researchers say they have created embryos and stem cells using human cells and the egg cells of cows. But they say such experiments will not lead to hybrid human-animal babies, or even to direct medical therapies.

can the formation of such human-cow hybrid embryos be justified ethically? Not everyone agrees

Dr Lyle Armstrong of Newcastle University presented preliminary data on his work to Israel's parliament last week.

It has not been reviewed by other experts in the field, the university says, but the researchers intend to have their work peer-reviewed.

researchers say they have hollowed out the egg cells of cattle, inserted human DNA to create a growing embryo, and then taken it apart to get embryonic stem cells
There is no possibility of creating a human that is part-animal

They say the animal egg only acts as a shell for the human DNA.

the hybrid embryos will not be implanted and by law that any that are created have to be destroyed at 14 days.
