You're about 10 years behind the times, C/L. In the past, stem cells were extracted from "leftover embryos" from people who underwent fertility treatments. Such transfer was always done with the consent of the donors. Far from being young human beings these were embryos that no one had any further use for and which would have been discarded.
Now stem cells are extracted from the hosts themselves. The primary benefit is that since the cells are part of the body the odds of rejection are substantially reduced. As I noted above, we did this with a dog and no puppies were harmed in the process.
