Frequency of Tregs generated in ACI recipients. a Representative dot plots of splenic Tregs. Percentages of CD4+CD25+Foxp3+ T cells are indicated in the top right corners of each dot plot. b Graphic results of frequency of splenic CD4+CD25+Foxp3+ T cells. Results are representative of five independent experiments. *p < 0.05 vs untreated; # p < 0.05 vs MSC. c Graphical representation of numbers of Foxp3+ T cells (cells/mm2) within the liver allografts. The results are representative of six separate experiments. *p < 0.05 vs untreated; # p < 0.05 vs MSC. d Representative immunohistochemistry staining of intragraft Foxp3+ T cells.
