If you want "consistent" fetal stem cells, you will see scientists cloning (so that the baby is a known quality rather than taking whatever random DNA you wind up with, also they can patent a clone configuration).
We are told that the "experimental" cells comes from "ethical" sources but the elephant in the room they won't admit to seeing is that IF such treatments become industry standard, they will need to harvest fetuses (create life specifically to destroy it) to meet market demand.
Excellent observation! Thanks for the ping and post.
