There a lot of ethical concerns about stem cell research. Many have to do with the destruction of embryos for embryonic stem cell research. Those of us who oppose embryo destructive research frequently promote the potential for adult stem cell research as a better and less ethically problematic alternative. But adult stem cell therapy has a different problem. It is becoming the most recent version of snake oil.
While legitimate research involving adult stem cells should be supported, everyone from Texas Governor Perry to Indianapolis Colts quarterback Peyton Manning have been getting unproven adult stem cell treatments outside of valid research protocols. Why would otherwise intelligent people subject themselves to unproven and potentially risky treatments?
Part of it may have to do with our human tendency to believe that something is true when we strongly desire for it to be true. Our desires can be so strong they cloud our ability to reason and there are plenty of people who understand they can take advantage of that for their own profit. They sell everything from snake oil to mangosteen juice to stem cells to people whose desire for a cure makes them vulnerable.
Another part may be our society’s unrealistic belief that scientific medicine should be able to cure everything. Researchers’ hopeful expression of what may be possible with treatments such as stem cell therapy can make people with medical problems for which there are not effective treatments susceptible to trying an unproven treatment because of that potential.
Then again there is always the possibility that an unproven treatment may work. Snake oil was actually a traditional Chinese remedy that used the fat of the Chinese water snake that was high in a prostaglandin precursor to help relieve inflamed joints. When used correctly it may work. Adult stem cell therapy may turn out to be effective for some of the things it is being used for by those selling unproven treatments. But we won’t know unless those treatments are done in properly controlled trials.
