PRP stands for platelet rich plasma and involves a simple blood draw from the patient. This blood is placed into a kit and spun quickly for 10-15 minutes in a centrifuge machine. What this does is separate the blood into several layers. The middle layer is termed the “buffy coat” and contains concentrated platelets, white blood cells, and 8-12 growth factors. There are minimal stem cells in PRP, if any, so it is a very helpful regenerative biologic but not a stem cell therapy.
Amniotic and umbilical cord materials contain over 80 growth factors along with an extensive amount of cytokines, mRNA, exosomes, secretomesand additional biologic elements including stem cells. The amount of these elements varies depending on the lab that processes the material and depends on the amount of preservative, radiation, etc.
