In vivo influence of Platelet-Rich Fibrin (PRF) on experimentally generated wounds. Experimentally generated bilateral gluteal wounds (biopsy punch, Ø 4 mm) of 10 test persons were treated by day 0 and day 5 with Vivostat PRF® or NaCl 0.9% as control. After 10 days, wound areas were resected (biopsy punch, Ø 6 mm) and gene expression of the indicated factors was determined by real-time PCR (* p < 0.05, Student’s t-test).
