This medication is derived by taking the patient's blood and placing it in a centrifuge to separate out various components, yielding a substance that has a five times greater concentration of platelets (a special type of blood cell) than ordinary blood. Because platelets contain large amounts of growth factors and other growth-promoting proteins, platelet-rich plasma will stimulate the growth of healthy tissue when injected into the patient's wound. One version of PRP is autologous, meaning that it's derived from the patient's own blood and therefore has no risk of any adverse reactions. Another version of PRP, derived from donor plasma, also appears to be very safe and effective. We are currently conducting several clinical trials on the wound-healing benefits of both forms of PRP.
