Recovery of mouse knee joints. (A) The cartilage layer of 15% platelet-rich plasma (PRP)-cultured adipose-derived stem cell (ADSC)-treated mice was similar to that in normal mice. There was evidence of regenerated cartilage formation at the articular cartilage margin in the treated mice, and the thickness of the cartilage layer of the treated mice compared with (B) before treatment and (C) control. H & E-stained articular cartilage sections of mice that received (D, E) 15% PRP-cultured ADSC transplantation, (F) 10% fetal bovine serum (FBS)-cultured ADSC transplantation, or (C) PBS injections.
