Platelet-derived growth factor subunit A (PDGFA); belongs to the PDGF/VEGF growth factor family. PDGFA is a secreted protein; stored in platelet alpha-granules and released by platelets upon wounding. PDGFA is potent mitogens for a variety of cell types including smooth muscle cells; connective tissue cells; bone and cartilage cells; and some blood cells. It plays an essential role in the regulation of embryonic development; cell proliferation; cell migration; survival and chemotaxis. PDGFA is required for normal lung alveolar septum formation during embryogenesis; normal development of the gastrointestinal tract; normal development of Leydig cells and spermatogenesis; normal oligodendrocyte development and normal myelination in the spinal cord and cerebellum. It plays an important role in wound healing; Signaling is modulated by the formation of heterodimers with PDGFB.
Measured in a cell proliferation assay using BALB/C?3T3 mouse fibroblast cells. The ED50 for this effect is 100-400 ng/ml.
Endotoxin:
