Stem cell therapy outside of bone marrow transplants have not been approved by the FDA in the US. Some limited use of umbilical chord blood for specific disease entities have been allowed, but mostly in clinical trial environments. Stem cells, sometimes called the body’s “master cells,” are the precursor cells that develop into blood, brain, bones and all of your organs. Their promise in medical treatments is that they have the potential to repair, restore, replace and regenerate cells that could then be used to treat many medical conditions and diseases. The problem is that cancers in general have now been shown to develop from these same stem cells, and when "traumatized" as in the injection process, they can easily mutate into cancerous counterparts of their intended regenerative targets.
Platelet-rich plasma is quite different. Blood is made of red blood cells, white blood cells, plasma, and platelets. Platelets were initially known to be responsible for blood clotting. In the last 20 years we have learned that when activated in the body, platelets (naturally mobilized in the body) create controlled inflammation and release healing proteins called growth factors. There are many growth factors with varying responsibilities, however cumulatively they accelerate tissue and wound healing. Therefore, under an unproven premise thus far, after increasing the baseline concentration of these platelets with platelet-rich plasma (an artificial process), we are able to deliver a powerful cocktail of growth factors that can theoretically dramatically enhance tissue recovery.
