title: Role of platelet derived growth factor in bone cell function.
abstract: PDGF is a mitogen for cells of the osteoblastic lineage. PDGF is present in the systemic circulation and is locally synthesized by skeletal cells. The systemic form primarily contains PDGF B chains, which are intrinsically more active than PDGF A subunits, the forms secreted by normal bone cells. PDGF AA is regulated by other growth factors and cytokines, which modulate its binding to osteoblastic receptors and its synthesis by skeletal cells. The exact role of PDGF in bone remodelling is still uncertain and current information suggests that this factor has a function in the response to inflammation and wound healing.
