Abstract:
PURPOSE: Although platelet-rich plasma (PRP) potentiate the wound healing activity of adipose-derived stem cells (ADSCs), its effect cannot be sustained for a prolonged period of time due to short duration of action. This led us to design and produce platelet-rich fibrin (PRF), in an effort to develop a tool which lasts longer, and apply it on wound healing. METHODS: Two symmetrical skin defects were made on the back of seven nude mice. ADSCs were applied to each wound, combined with either PRP or PRF. The wound area was measured over 14 days. By day 16, the wound was harvested and histologic analysis was performed including counting of the blood vessel. RESULTS: The healing rate was more accelerated in PRP group in the first 5 days (p<0.05). However, PRF group surpassed PRP group after 6 days (p<0.05). The average number of blood vessels observed in the PRF group was 6.53 +/- 0.51, compared with 5.68 +/- 0.71 for the PRP group. CONCLUSION: PRF exerts a slow yet pervasive influence over the two-week course of the wound healing process. Thus, PRF is probably more beneficial for promoting the activity of ADSCs for a sustained period of time.
