Thus, it can be established by this study that regenerative ability of autologous PRP by virtue of multitude of growth factors present in it, the most important being IGF, PDGF and FGF, is responsible for increased production and better organization of collagen fibers in experimental models of injured ATE.
* Lyophilized authentic human Polypeptide Growth Factors: Adiponectin, BMP2, EGF, FGF1, FGF2, FGF7, FGF10, Fallistatin, Gremlinl, hGH, hPL, Irisin, Midkine, PDGF, PRL, SCF, TGFb1, TGFb3, TIMP2, Thymosin-b4, VEGF, VIP
L-PRF contains PDGF, TGF-[beta], insulin-like growth factor, VEGF, fibroblast-derived growth factor, and epidermal growth factor.
Platelet-derived growth factor (PDGF) stimulates PDGF receptor subunit dimerization and intersubunit trans-phosphorylation.
Cell supernatants were collected, and HMGB1, TGF-[beta]1, and PDGF levels were measured using HMGB1, TGF-[beta]1, and PDGF ELISA kits, respectively, according to the manufacturer's instructions.
Also, PDGF BB was overexpressed in all types of cells (mesenchymal cells P = 0.009, endothelial cells P = 0.001, and macrophages P = 0.0001) in scars with no residual tumor (Figure 3(g)-3(i)) and in scars in female patients (mesenchymal cells P = 0014, endothelial cells P < 0.001, and macrophages P <0.0001) (Figures 3(j)-3(l)).
Our results suggest that CF plays a crucial role during EMT and that blocking it attenuates EMT by simultaneously suppressing the activation of TGF-[sz] and PDGF signaling pathways.
PRF also releases growth factors such as PDGF and TGF which promote periodontal regeneration.
It also reported that PDGF expressed in dorsal horn neurons contributes to neuropathic pain after nerve injury, (22) though how PDGF produces pain hypersensitivity remains unknown.
PDGF is secreted after tissue damage and promotes cellular reactions throughout all phases of the wound healing process.
Furthermore, platelets have been identified as producers of high quantity of growth factors, such as Platelet Derived Growth Factor (PDGF), Transforming Growth Factor-B1(TGF), TGF-B2, Fibroblast Growth Factor (FGF), Vascular Endothelial Growth Factor (VEGF), Insulin-like Growth Factor (IGF) that stimulate cellular proliferation, matrix remodeling and neo-angiogenesis (Dohan Ehrenfest et al., 2010; Farina et al., 2013).
The benefit for the patient is that platelet-rich plasma contains growth factors, FGF and PDGF, which can aid in the repair process of tissue and skin.
