PRP(富血小板血浆)为自体血液经离心、提取获得的含有大量血小板的血浆成分，其中所含有的血小板比正常人血浆中的血小板含量显著更高。血小板是直径小于2μm的非常小的血细胞，通常肉眼看不见，正常人血液中至少为每1μl含有十万到十五万个血小板。根据PRP中白细胞与纤维蛋白的含量可以将其分为多种类型，如去白细胞PRP、富白细胞PRP、去纤维蛋白PRP与富血小板纤维蛋白PRP等。PRP中的生长因子(growthfactors，GFs)非常丰富，主要是通过活化后血小板释放的α-颗粒产生，如血管内皮生长因子、血小板源性生长因子、转化生长因子-β3等等，这些因子对于创伤愈合、组织修复都有着有益的作用。除此之外，PRP所含有的生长因子，如胰岛素样生长因子(IGF)、转化生长因子β与成纤维细胞生长因子能促进间充质干细胞中Col-II和蛋白酶的表达，促进软骨细胞增殖、调节间充质干细胞分化的能力以及细胞外基质合成，进而参与到组织损伤的修复、关节软骨缺损、骨缺损、创面愈合当中。PRP (Platelet Rich Plasma) is a plasma component containing a large number of platelets obtained by centrifugation and extraction of autologous blood, and the platelet content contained in it is significantly higher than that in normal human plasma. Platelets are very small blood cells with a diameter of less than 2 μm, usually invisible to the naked eye, and normal human blood contains at least 100,000 to 150,000 platelets per 1 μl. According to the content of white blood cells and fibrin in PRP, it can be divided into various types, such as leukocyte-reducing PRP, leukocyte-rich PRP, defibrin PRP and platelet-rich fibrin PRP. Growth factors (growth factors, GFs) in PRP are very rich, mainly produced by α-granules released by platelets after activation, such as vascular endothelial growth factor, platelet-derived growth factor, transforming growth factor-β3, etc. It has beneficial effects on healing and tissue repair. In addition, the growth factors contained in PRP, such as insulin-like growth factor (IGF), transforming growth factor β and fibroblast growth factor can promote the expression of Col-II and protease in mesenchymal stem cells, and promote the proliferation of chondrocytes , regulate the differentiation ability of mesenchymal stem cells and the synthesis of extracellular matrix, and then participate in the repair of tissue damage, articular cartilage defects, bone defects, and wound healing.
