Millions and millions of dollars have been spent to get this type of technology to market, but since Johoda’s successful stem cell transplant in the 1980s, there is still not a single technology available that is marketed with good science behind it. There are, however, may stem cell treatments that are being marketed by sham doctors who claim that these treatments work just to make $$$. I always tell my patients, “Let the buyer beware,”¬†or that there are scams out there.
