Allograft rejection in the four groups. (A) Skin allograft appearance of the four groups from day 7 to 21 post-transplantation. (B) Different score levels indicate different necrotic areas of the mouse skin allograft (*: P < 0.05 comparison between the control group and adipose-derived stem cell [ADSC] injection groups). (C) The graft survival rates in four groups, which were evaluated by the Kaplan-Meier method. ADSC infusion markedly improved the skin allograft compared to that in the control group (P < 0.05). However, among the three ADSCs injection groups, there were no significant differences (P > 0.05).
