Platelet-derived growth factor (PDGF) is a dimeric molecule that exists in homodimers or heterodimers of related polypeptide chains (A and B). Two types of PDGF receptors have been identified.

Platelet-Derived Growth Factor (PDGF) Signaling Network. Platelet-derived growth factor (PDGF) signaling network consists of four ligands, PDGFA-D, and two receptors, PDGFRalpha and PDGFRbeta. All PDGFs function as secreted, disulphide-linked homodimers, but only PDGFA and B can form functional heterodimers.

Platelet-derived growth factor (PDGF) is a potent mitogen, chemoattractant, and survival factor for cells of mesenchymal origin (such as fibroblasts, smooth muscle cells, or glial cells). PDGF exists as a number of isoforms that initiate signaling via two closely related receptor tyrosine kinases named α - and β -receptors. Platelet-Derived Growth Factor is the principal mitogen found in mammalian serum and is released from platelets during clot formation. 1 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.

this study shows that the expression of PDGFB is significantly downregulated in keloid fibroblasts compared to normal human fibroblasts. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds.

This gene encodes a member of the protein family comprised of both platelet-derived growth factors (PDGF) and vascular endothelial growth factors (VEGF). The encoded preproprotein is proteolytically processed to generate platelet-derived growth factor subunit A, which can homodimerize, or alternatively, heterodimerize with the related platelet-derived growth factor subunit B.

The synthesis of PDGF can be induced by IL-1, IL-6, TNF-α, TGF-β and EGF. Regenerative medicine for bone tissue mainly depends on efficient recruitment of endogenous or transplanted stem cells to guide bone regeneration. Platelet-derived growth factor (PDGF) is a functional factor that has been widely used in tissue regeneration and repair.

Platelet Derived Growth Factor (PDGF) Family PDGFs are potent mitogens acting on cells of mesenchymal origin, like fibroblasts and smooth muscle cells (Yu et al. 2003). The family of PDGFs is comprised of four factors: PDGF-A, B, C and D (LaRochelle et al. 2001).

Platelet-derived growth factor (PDGF) was identified more than three decades ago as a serum growth factor for fibroblasts, smooth muscle cells (SMCs), and glia cells (Kohler and Lipton 1974; Ross et al. 1974; Westermark and Wasteson 1976). Platelet-Derived Growth Factor (PDGF) Receptor Alpha PDGF receptor alpha, also known as PDGFRA and CD140a, is a tyrosine-protein kinase that acts as a cell-surface receptor for PDGFA, PDGFB and PDGFC. PDGFRA plays an essential role in the regulation of embryonic development, cell proliferation, survival and chemotaxis.

Complete growth factors are not released by platelet disruption or fragmentation. Instead, these growth factors are actively extruded through the cell membrane where histones and carbohydrate side chains are added to complete their unique chemistries and make them “active” growth factors.

PDGF stimulates chemotaxis, proliferation, and new gene expression in monocytes-macrophages and fibroblasts in vitro, cell types considered essential for tissue repair. El PDGF tiene unos pocos miembros en la familia, por ejemplo la sub familia del Factor de crecimiento endotelial vascular (VEGF, por vascular endothelial growth factor).
