Platelet-derived growth factor.
Platelet-derived growth factor was purified from fresh platelets by a large-scale procedure not involving the use of SDS (sodium dodecyl sulphate). The product, 0.5 mg of platelet-derived growth factor, obtained from about 3 x 1013 platelets migrated as a single component in analytical gel electrophoresis in the presence of SDS and showed no inhomogeneity on sedimentation-equilibrium analysis i...
متن کاملSignal transduction by the receptors for platelet-derived growth factor.
Platelet-derived growth factor (PDGF) is a connective tissue cell mitogen that originally was purified from human platelets, but recently has been found to be produced by many different cell types (reviewed by Ross et al. 1986; Heldin and Westermark, 1989). The in vivo function of PDGF remains speculative, but the fact that PDGF is released by platelets and by cells involved in the inflammatory...
متن کاملPlatelet-derived growth factor promotes polymorphonuclear leukocyte activation.
The platelet-derived growth factor (PDGF) has several well defined important biologic activities. Platelet-derived growth factor is the major mitogen in human serum for cells of mesenchymal origins; it is a potent chemoattractant protein for human monocytes, neutrophils, fibroblasts, and smooth muscle cells; and has been implicated in transformation by simian sarcoma virus and perhaps in transf...
متن کاملVascular endothelial growth factor can signal through platelet-derived growth factor receptors
Vascular endothelial growth factor (VEGF-A) is a crucial stimulator of vascular cell migration and proliferation. Using bone marrow-derived human adult mesenchymal stem cells (MSCs) that did not express VEGF receptors, we provide evidence that VEGF-A can stimulate platelet-derived growth factor receptors (PDGFRs), thereby regulating MSC migration and proliferation. VEGF-A binds to both PDGFRalp...
متن کاملPlatelet-derived growth factor in human glioma.
Platelet-derived growth factor (PDGF) is a 30 kDa protein consisting of disulfide-bonded dimers of A- and B-chains. PDGF receptors are of two types, alpha- and beta-receptors, which are members of the protein-tyrosine kinase family of receptors. The receptors are activated by ligand-induced dimerization, whereby the receptors become phosphorylated on tyrosine residues. These form attachment sit...
