If they put the embryo inside human womb, what is the result?
From New Scientist:
"Scientists in the UK applied on Monday for permission to create part-cow, part-human embryos for research aimed at treating diseases such as Parkinson's and Alzheimer's.
The procedure would involve inserting human DNA into cows’ eggs that have had their own genetic material removed. The embryos created from this process would then be almost entirely “human”, with the only cow DNA being outside the cells’ nuclei.
If they manage to pull off the feat, the human-bovine embryos would not be allowed to develop for more than a few days, the researchers say.
The hybrid embryos would be used to produce embryonic stem cells, which have huge potential for treating disease. At present, embryonic stem cells have to be obtained from unwanted early stage human embryos left over from in-vitro fertilisation treatments. Using cow eggs would potentially give researchers a far greater supply of stem cell material."
