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 کاملPlatelet-derived growth factor and transforming growth factor-beta enhance tissue repair activities by unique mechanisms
Platelet-derived growth factor (PDGF) and transforming growth factor-beta (TGF-beta) markedly potentiate tissue repair in vivo. In the present experiments, both in vitro and in vivo responses to PDGF and TGF-beta were tested to identify mechanisms whereby these growth factors might each enhance the wound-healing response. Recombinant human PDGF B-chain homodimers (PDGF-BB) and TGF-beta 1 had id...
متن کاملSelective Upregulation of Platelet-derived Growth Factor c~ Receptors by Transforming Growth Factor/~ in Scleroder Fibroblasts
Transforming growth factor B (TGF-~), a multifunctional cytokine, is an indirect mitogen for human fibroblasts through platelet-derived growth factor (PDGF), particularly the A ligand-c~ receptor arm of that system. TGF-~ effects on PDGF ot receptor expression were studied in vitro using ligand binding techniques in three human dermal fibroblast strains: newborn foreskin, adult skin, and sclero...
متن کاملExpression of transforming growth factor-beta and platelet-derived growth factor in linear scleroderma.
Linear scleroderma (LS) is a localized form of scleroderma characterized by mononuclear cell infiltration and fibroblast proliferation. In the later stages of the disease, excessive collagen is deposited with concomitant skin and appendage atrophy. These symptoms suggest a breakdown of fibroblast cell function, and consequently, growth factors have been thought to play a role in the pathogenesi...
متن کاملDipyridamole decreases platelet-derived growth factor levels in human serum.
Mitogenic activities on confluent fibroblasts by sera from patients with scleroderma and normal controls were studied. In experiments using eight different fibroblast strains (one human fetal lung fibroblast, one foreskin fibroblast, three adult skin fibroblast, and three scleroderma fibroblast), pooled scleroderma serum showed lower mitogenic activity by 3H-thymidine incorporation assay than p...
