Effect of catalpol on caspase-3 expression in human induced pluripotent stem cells with aconitine-induced cardiac arrhythmia. Catalpol treatment reduced the percentage of caspase-3-positive cells by 12.7, 39.9, and 71.82% at 1, 10, and 100 µM concentrations, respectively. a Immunofluorescent images of caspase-3-positive cells. b Percentage analysis of caspase-3-positive cells. ***P < 0.001 vs. Group I; #P < 0.05 and ###P < 0.001 vs. Group II. Scale bar is 50 µm
