Figure 3.

Effect of co-culturing on apoptosis of Th1 and Th2 cells. Apoptosis rates were assessed after 24 h by flow cytometric analysis of caspase-3 staining in CD4⁺ T lymphocytes cultured alone or co-cultured with activated hepatic stellate cells (n = 10). Data are expressed as mean ± SD; ^bP < 0.01 vs control.
