There are gray areas within the larger stem cell sphere or as I called it in a recent paper “the stem cell ecosystem“, but chiropractors doing stem cell transplants is not one of them. This is unethical and risky on many levels, but the number of chiropractors selling stem cells is increasing rapidly nonetheless. Chiropractors who are selling stem cells should stop and their organizations should prohibit it. The money involved makes it likely that somehow they will have to be forced to stop.
