Growth factor levels in lysates after the activation of platelet-poor plasma (PPP) and platelet-rich plasma (PRP). (A) Insulin-like growth factor 1 (IGF-1), (B) hepatocyte growth factor (HGF), (C) platelet-derived growth factor (PDGF), (D) transforming growth factor beta (TGF-β), and (E) vascular endothelial growth factor (VEGF) protein levels were measured in duplicate by enzyme-linked immunosorbent assay (ELISA) in the PRP and PPP lysates. Any statistical significance of the differences between PPP and PRP was determined by t-test (* p < 0.05; *** p < 0.001; **** p < 0.0001) (n = 5).
