Platelet-derived Growth Factor Is Chemotactic for Fibroblasts
Chemotaxis assays in modified Boyden chambers were used to detect fibroblast chemoattractants in materials released from early-stage inflammatory cells, namely, mast cells, platelets, and neutrophils. Strong attractant activity was found in substances released from platelets. This activity was accounted for mainly by the platelet-derived growth factor (PDGF), which is released from the platelet...

متن کاملSelective upregulation of platelet-derived growth factor alpha receptors by transforming growth factor beta in scleroderma fibroblasts
Transforming growth factor beta (TGF-beta), a multifunctional cytokine, is an indirect mitogen for human fibroblasts through platelet-derived growth factor (PDGF), particularly the A ligand-alpha receptor arm of that system. TGF-beta effects on PDGF alpha receptor expression were studied in vitro using ligand binding techniques in three human dermal fibroblast strains: newborn foreskin, adult s...
متن کاملPlatelet-derived growth factor alpha and beta receptors have overlapping functional activities towards fibroblasts
BACKGROUND Platelet-derived growth factor (PDGF) signalling is essential for many key cellular processes in mesenchymal cells. As there is redundancy in signalling between the five PDGF ligand isoforms and three PDGF receptor isoforms, and deletion of either of the receptors in vivo produces an embryonic lethal phenotype, it is not know which ligand and receptor combinations mediate specific ce...
متن کاملPlatelet Derived Growth Factor Alpha (PDGFRα) Induces the Activation of Cardiac Fibroblasts by Activating c-Kit
BACKGROUND Enhanced platelet-derived growth factor receptor a (PDGFRα) signaling pathway activity leads to cardiac fibrosis. However, because of the pleiotropic effects of PDGFR signaling, its role in mediating the cardiac fibrotic response remains poorly understood. This study aimed to investigate the regulatory effect of c-Kit in cardiac fibroblasts activated by PDGFRa signaling. MATERIAL AND...
