Other growth factor receptors in Platelet-Rich Plasma

Other growth factor receptors in Platelet-Rich Plasma (PRP) refers to a collective group of transmembrane proteins that mediate the biological effects of the various signaling molecules found within concentrated platelets [1]. PRP contains a high concentration of growth factors, including Platelet-Derived Growth Factor (PDGF), Transforming Growth Factor-beta (TGF-beta), Vascular Endothelial Growth Factor (VEGF), and Insulin-like Growth Factor (IGF) [2]. These factors bind to their respective receptors—such as PDGFR, TGFbetaR, VEGFR, and IGFR—on the surface of target cells like fibroblasts and mesenchymal stem cells [3]. These receptors are primarily receptor tyrosine kinases or serine/threonine kinases that, upon activation, trigger intracellular cascades such as the MAPK and PI3K/Akt pathways [2]. This coordinated signaling promotes essential regenerative processes including cell proliferation, chemotaxis, extracellular matrix synthesis, and angiogenesis [4]. Because PRP is a complex biological product rather than a single molecule, this target represents the integrated response of multiple receptor systems working synergistically to facilitate tissue healing [1]. It is commonly discussed in the context of regenerative medicine for treating conditions like osteoarthritis, tendon injuries, and chronic wounds [3]. Consequently, it is not considered a single therapeutic target in the traditional pharmacological sense but rather a descriptive category for the multi-receptor mechanism of PRP therapy [4].
