do adult stem cells harm people ? or is it only the embryonic ones that are surrounded by controversy?
The controversy is not about whether or not they are harmful(although they’re pretty close to cancer cells and could be harmful)
It’s that to isolate embryonic stem cells….they must be harvested from an embryo.
Researchers have been using “adult” or somatic stem cells for decades. So far we’ve learned a lot but have not made considerable advances. It’s thought that embryonic stem cells…which have not differentiated as much as somatic stem cells….may be used to cure things like disease and paralysis.
The embryos researchers want to use are destined for the garbage can anyways but the conservatives in government claim each embryo is a human life and cannot be used.
