Abstract

Abstract Background: Epithelialization is an indicator of wound healing. Platelet-rich plasma (PRP) may accelerate the epithelialization of the wound due to high amount of growth factors. Generally, allogeneic PRP provides a smaller immunological effect than autologous PRP. By a freeze-drying method, it is assumed that allogeneic PRP has lower allergenic activity. Aims and Objectives: The aim of this study was to investigate the effect of allogeneic freeze-dried PRP on wound healing of a full-thickness wound in New Zealand rabbits. About 2 × 2 cm2 full-thickness wounds were created on rabbits using a template on both sides of the dorsum and divided into treatment group and control group. The treatment group was treated with allogeneic freeze-dried PRP and the control group was treated with moist dressing. Acceleration of wound healing was shown by the epithelialization and measured on day 7 using digital Visitrak. Nine New Zealand rabbits were used in this study. Results: In the treatment group, the epithelialization was significantly higher 3.00 ± 0.96 cm2 than the control group 1.35 ± 0.85 cm2 (P < 0.000) by independent t test. Another finding of our study was the allergic reaction was not observed after the administration of allogeneic freeze-dried PRP in rabbits. Conclusion: Our results indicate that allogeneic freeze-dried PRP accelerates epithelialization compared to the control group and does not cause an allergic reaction in full-thickness wounds in rabbits. The effect of allogeneic PRP, prepared with a freeze-drying method, on the process of wound healing is reported for the first time in this article.
