Activated rat hepatic stellate cells influence Th1/Th2 profile in vitro

Figure 2 Effect of co-culturing on Th1/Th2 profile. A: Proportion of CD4⁺ T lymphocytes identified as Th1 and Th2 cells; B: Mean fluorescence intensity of interferon (IFN)-γ in Th1 cells and interleukin (IL)-4 in Th2 cells assessed by flow cytometry when cultured alone or co-cultured for 48 h with activated hepatic stellate cells (n = 10). Data are expressed as mean ± SD. ^aP < 0.05, ^bP < 0.01 vs control.
