BM-MSCs increased the percentage of M2 macrophages in transplanted fat. a The effects of PBS or BM-MSCs on transplanted macrophages and M2 macrophages were labelled with MAC2 + (red) and CD206 + positive (green) staining. Scale bar 50 um. b, c Compared with the PBS control group, the ratio of CD206 + M2 macrophages increased rapidly on days 14 of transplantation in the BM-MSCs group, and stabilized on days 30 and 90. The ratio of CD206 + M2 macrophages was still high in PBS group. n = 6 per group. *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001
