I think that may be an overstatement. I spoke to a doc about stem cell therapy and he said that people only did it through trials. IT is very expensive because they do have to wipe out your immune system to try to reboot with stem cells. During this time, they keep you in a hospital on the transplant ward where you are basically in a plastic bubble. I didn't get numbers of fatalities with this process but it was the doctors opinion that those young and healthy enough wasn't ready for the risk, and the ones farther along where ready for the risk, but would have a harder time.
My Neuro has performed stem cell treatment many times and swears by it, but , Australia have now banned it so we can't have it anymore. Damned do good ears say it is unethical. They use your own stem cells, so go figure.
