Platelet-derived Growth Factors and Tissue Repair / 中国康复理论与实践

@#Platelet-derived growth factors (PDGFs) are a member of family of glycoprotein dimers (Mr 27000～35000) that exert potent mitogenic and chemotactic activities toward cells of mesenchymal origin. The PDGFs possess a myriad of critical roles in embryonic development,cellular differentiation and response to tissue damage. It is one of the growth factors,which appear early during the process of wound healing. Especially,PDGFs can effectively promote the healing of some chronic refractory wounds,such as diabetes mellitus ulcer,chronic venous ulcer,bedsore,radioactivity ulcer,etc..
