Would an embryo about to die choose life in a trash can or life on a petri dish?
Is potential enough alone?
So do we experiment on it or do we let it die?
Would that be human cruelty?
How do adult stem cells evolve during development and how are they maintained in the adult? Are they "leftover" embryonic stem cells, or do they arise in some other way?
What would happen if embryonic stem cells prove to cure all the diseases it promises to? How will we be able to keep producing embryonic stem cells at the rate of the demand?
