Background
PRP (platelet rich plasma) is a plasma component obtained by centrifuging and extracting autologous blood and containing a large amount of platelets, which are significantly higher than the level of platelets in normal human plasma. Platelets are very small blood cells less than 2 μm in diameter, usually invisible to the naked eye, and at least one hundred thousand to fifteen thousand platelets per 1 μ l of normal human blood. The PRP can be classified into various types according to the content of leukocytes and fibrin, such as leukocyte-depleted PRP, leukocyte-enriched PRP, fibrin-depleted PRP, and platelet-enriched fibrin PRP. The Growth Factors (GFs) in PRP are very abundant and are mainly produced by the α -granules released from platelets after activation, such as vascular endothelial growth factor, platelet-derived growth factor, transforming growth factor- β 3, etc., which have beneficial effects on wound healing and tissue repair. In addition, the growth factors contained in PRP, such as insulin-like growth factor (IGF), transforming growth factor beta and fibroblast growth factor, can promote the expression of Col-II and protease in mesenchymal stem cells, promote the proliferation of chondrocytes, regulate the differentiation capacity of mesenchymal stem cells and the synthesis of extracellular matrix, and further participate in the repair of tissue injury, articular cartilage defect, bone defect and wound healing.
