 This study investigated the effects of autologous blood preparations containing platelet-rich plasma, PRP, on the levels of growth factors and platelet concentration. The results showed that the platelet count in the PRP group was significantly higher than that of the whole blood group. Additionally, the levels of PDGFAB and PDGFBB were also found to be higher in the PRP group compared to the other groups. These findings suggest that PRP may have potential benefits for wound healing and tissue repair.
