Rabbit study: Levels of cytokines in platelet-rich fibrin (PRF) gel. (A) Platelet-derived growth factor beta beta (PDGF-BB), (B) transforming growth factor beta-1 (TGF-Ī²1) and (C) Insulin-like growth factor 1Ā (IGF-1). All values are presented as meansāĀ±āstandard deviations across six rabbits. The extrudate of the PRF close to the red blood cell end is denoted as clot1. The extrudate of the PRF gel after a second centrifugation is denoted as extract1. Serum was obtained from clotted whole blood after an initial centrifugation. Concentrations of PDGF-BB and TGF-Ī²1 in clot1 were always three to four times higher than those in extract1, which were similar to those in serum.
