Shikonin prolongs skin allograft survival and reduces CD3+ T cell infiltration in skin allografts. (A) C57BL/6 mice were transplanted with a skin allograft from a BALB/C donor and treated without or with shikonin or CsA (20 mg/kg). The survival times of the skin grafts were observed (*P < 0.05 and **P < 0.01, n = 8–9). H&E (B) and immunohistochemical staining for CD3 (C) were performed 10 days post-transplantation. (D) Transplanted mice were treated with shikonin plus low doses of CsA (10 mg/kg) and/or anti-CD45RA mAb (0.1 mg) to observe the effects of the double or triple treatments on skin allograft survival (**P < 0.01, n = 8–9).
