Platelet-Rich Fibrin Improves Fat Graft Survival Possibly by Promoting Angiogenesis and Adipogenesis, Inhibiting Apoptosis, and Regulating Collagen Production

Abstract

PRF can promote autocrine function of the grafted fat to produce more growth factors. It greatly increased fat retention rate, possibly by promoting vascularization and adipogenic differentiation, inhibiting cellular apoptosis, and regulating collagen production.
