Abstract
Objective: To observe the effects of platelet-rich plasma (PRP) on in vitro proliferation and migration of fibroblasts from human chronic refractory wound granulation tissue.Methods: Fibroblasts were separated from human chronic refractory wound granulation tissue and then were identified. The obtained fibroblasts were divided into fetal bovine serum (FBS) group, hydrogel group and PRP group, and the three groups were cultured with culture mediums containing FBS, hydrogel and PRP respectively, in order to observe the growth of fibroblasts. The wound scratch assay was used to observe the migration of fibroblasts.Results: PRP group had more fibroblasts than FBS group and hydrogel group since Day 5 of culture, and exhibited greater fibroblast scratch migration area than FBS group on 48 h and 72 h of wound scratch assay (all p < .05).Conclusions: Compared with FBS, human fibroblasts cultured by PRP can more effectively promote the proliferation and migration of fibroblasts.
