PRP promotes fibroblast proliferation in vitro. (A) The proliferation of fibroblasts among the 6 groups was measured by CCK-8. (B) Flow cytometry was used to assess the stage of cells. (C) The levels of cyclin D1 and cyclin D3 were measured by western blot analysis. (D) qRT-PCR analysis was applied to detect the expression of cyclin D1 and cyclin D3 in control and PRP groups. * P<0.05, **** P<0.0001. PRP – platelet-rich plasma CCK-8 – Cell Counting Kit-8; qR-PCR – quantitative real-time polymerase chain reaction.
