Platelet-Derived Growth Factor from porcine platelets

Application
PDGF elicits multifunctional actions with a variety of cells, including mitogenesis of mesoderm-derived cells, increased extracellular matrix synthesis, and chemotaxis and activation of neutrophils, monocytes and fibroblasts.
Biochem/physiol Actions
The principal mitogen found in mammalian serum, released from platelets during clot formation. Elicits mitogenesis of mesoderm-derived cells, increased extracellular matrix synthesis, and chemotaxis and activation of neutrophils, monocytes and fibroblasts. Mitogenic for dermal and tendon fibroblasts, vascular smooth muscle cells, glial cells and chondrocytes. Appears to interact with transforming growth factor-β1 in accelerating wound healing. However, platelet-derived growth factor (PDGF) may also be pathogenic in arteriosclerosis and neoplasia.
Physical form
Lyophilized from a 0.2 μm filtered solution in 40% acetonitrile and 0.1% trifluoroacetic acid, pH 2.0.
Analysis Note
The mitogenic activity is tested in culture using Swiss 3T3 cells or NR6-3T3 fibroblasts.
