Flow cytometry analysis of the apoptosis rate of T cells after co-culturing with HSCs for 24 h. (A) Representative flow cytometry analysis of apoptotic T cells which were respectively co-cultured with HSCs from the tolerance group and rejection group. (B) Frequencies of apoptotic T cells after co-culturing with HSCs from the tolerance group and from the rejection group were analysed. Results are expressed as mean ± SD and are representative of five independent experiments. T cells co-cultured with HSCs from the tolerance group had a higher apoptosis rate than those co-cultured with HSCs from the rejection group. ^*P<0.05. HSCs, hepatic stellate cells.
