A short explanatory video/transcript describing what platelet-rich plasma (PRP) is, how it is prepared from a patient's blood, the role of platelets and their growth factors in tissue repair, common clinical uses (joint injections, soft-tissue repair, facial and hair rejuvenation), and a clear distinction that PRP is not stem cell therapy because it contains almost no cells.
So PRP stands for platelet rich plasma. So this is when a doctor draw your blood and thin it down. And the bottom is the red blood cells. On the top is the plasma. At the lower part of the plasma, where it's close to the blood cells, is the platelet rich portion. And why is platelet important? We all know when we get cut, platelets arrive on the scene. First they form the clot to prevent further bleeding, and then they release all these growth factors to help promote the healing of the tissue, forming lattices so we can form the new tissue. They do have a really important role in repair and is now widely used for joint ejections, soft tissue repair, even facial and hair rejuvenation. So they are fantastic, but they're not stem cell therapy, because there are almost no cells in it.
