Additional file 4 : Figure S4. Evaluation of the construction of mice intra-abdominal heterotopic cardiac transplantation model. A Flow cytometry analysis of CD68, CD16/32 and CD206 expressions of splenocytes isolated from HMC mice on day 7 and HTC mice on day 1, 3, 7 after transplantation. B The infiltration of iNOS+ (M1) and ARG-1+ (M2) macrophages in myocardial tissues were evaluated by IHC staining on day 7 in HMC group and on day 1, 3, 7 in HTC group after transplantation.
