Induction of dermal collagenesis, angiogenesis, and adipogenesis in human skin by injection of platelet-rich fibrin matrix
This clinical trial assessed the histological effects of autologous platelet-rich fibrin matrix (PRFM) injections in human skin. Four healthy adult volunteers received PRFM injections into the deep dermis and subdermis of the upper arms. Biopsies over a 10-week period revealed early fibroblast activation and collagen deposition by day 7, angiogenesis
