Fig. 4From: The toxicity of lithium to human cardiomyocytesLithium triggers the cell apoptosis of human cardiomyocytes. a Comparison of AC16 cell apoptosis treated with control or 5 mmol/L LiCl for 48 h via annexin V‐FITC/PI apoptosis assay. b Statistical analyses of the apoptotic cells in a. The data are represented as mean ± SEM (n = 3). **p < 0.01, ***p < 0.001. c Comparison of AC16 cell apoptosis treated with control or 2.5 mmol/L Li2SO4 for 48 h via annexin V‐FITC/PI apoptosis assay. d Statistical analyses of the apoptotic cells in c.
