PDGF-BB (Platelet-derived growth factor) comprises a family of homo or heterodimeric growth factors, including PDGF-AA, PDGF-BB, PDGF-CC, and PDGF-DD. • Binds to two different transmembrane tyrosine kinase receptors (PDGFR-alpha and PDFGR-beta) • Released from degranulating platelets and plays a role in each stage of wound healing • Stimulates mitogenicity and chemotaxis of neutrophils, macrophages, fibroblasts, and smooth muscle cells to the wound site • Enhances proliferation of fibroblasts and their production of extracellular matrix The biological activity of CTGrade GMP interleukins and growth factors is standardized, where applicable, to WHO International standards, providing cell and gene therapy developers consistent, lot-to-lot biological activity and performance.
