(A) Serum IL-6 concentration increased after mismatched BMSC transplantation (red) compared to syngeneic control (blue). Duplicate experiments. Data are shown as mean ± SD, n = 2. (B) GFP+ donor BMSCs appear in peripheral blood mononuclear cells after mismatched BMSCs transplantation, and peaks at approximately 7 weeks. The percentage of BMSCs expressing MHC class II antigen increases following transplantation. (C) CD4+ CD25+ Foxp3+ Tregs were suppressed in the spleen after mismatched WBMT transplantation (right) compared to syngeneic control (left). (D) CD4+CD25+Foxp3+ Tregs were suppressed in both mismatched WBMT (yellow) and mismatched BMSC transplantation (red) compared to syngeneic WBMT (green) or syngeneic BMSCs transplantation (blue). Data are shown as mean ± SD, triplicate experiments, n = 3–5, **p<0.01. (E, F) The ratio of CD4+ IL-17+ T cells in the spleen was significantly higher following mismatched WBMT (yellow) or mismatched BMSC transplantation (red) compared to syngeneic control (green and blue). Data are shown as mean ± SD, triplicate experiments, n = 3–5, *p<0.05. BMSCs, bone marrow stromal/stem cells; SD, standard deviation.
