At high concentration, human platelets can produce protein with cell adhesion function. When the pH value drops from 7.0-7.2 to 6.5-6.7, adding appropriate amount of calcium chloride can promote platelets to secrete a large number of nine growth factors that promote wound, tissue healing and cell regeneration, so PRP is also called "plasma rich in growth factors".
PRP can quickly stop bleeding, relieve pain, accelerate wound healing, and greatly reduce postoperative scar formation. Since the mid-1990s, PRP has been widely used in various surgical operations, heart surgery and plastic surgery, as well as medical beauty. Features: 1. In plasma with high platelet concentration, the platelet content is as high as 1 1,000,000 /mm3 (2-6 times that of ordinary blood).
2. The proliferation and differentiation of dermal stem cells are positively correlated with platelet concentration. When the plasma concentration reaches 4~5 times of the normal platelet concentration, it will cause cell proliferation and differentiation in excellent environment.
3. The PH value of plasma is 6.5~6.7, which can inhibit the growth of bacteria and promote the secretion of a large number of growth factors.
4. It contains nine kinds of autologous growth factors, which can promote cell regeneration and repair.
5. protein, which is rich in three kinds of macromolecules, A, elastic fiber, B, protein microfiber, C and endogenous microfiber, which are needed for cell adhesion proteins to form the three-dimensional structure of tissues.
6. Promote the effective proliferation of collagen III and IV.
7. High concentration and viscous self-adhesive can fill wrinkles, pits and scars.
