I agree that advancement saved your son. However, stem cells, like immunotherapy are not going to make people live forever. I think private researchers or private funding should be used for virtually all research because our government can't separate useful research from wasteful spending. This would increase efficiency for their use and the speed at which their purposeful use could dome to fruition. There is great potential for the research, but people who make these huge claims of unlimited potential are not well informed.
BTW I believe if a woman want to donate her cord cells after giving birth its her business and I believe a doctor should be able to ask her to donate it.
