Fig. 8: Effect of chloroquine pre-treatment on CCl4-induced cell apoptosis in liver tissues.

a Representative TUNEL-stained sections showing apoptosis in the liver tissue of mice from the vehicle and chloroquine (CQ) pretreated CCl4 groups (n = 4). Bar = 100 μm. b TUNEL-positive cells were counted and statistical analyses presented as mean ± SD. **P < 0.01, compared with the control group; #P < 0.05, compared with the CCl4 + vehicle group
