While the list of diseases for which stem cell treatments may be beneficial
is still very short, the most successes have been with blood stem cell
transplantation, as well as with some bone, skin, and eye injuries/diseases. As
of now, other uses for stem cells have yet to be proven in clinical trials even
though some companies are promoting "stem-cell therapies" for cosmetic and
various anti-aging treatments. Do you believe companies should provide
evidence of clinical successes or do you think people should be responsible for
researching what they purchase before they buy? Explain.
