Effect of matrine, oxymatrine, cytisine, and sophocarpine on cell viability and cell cytotoxicity in hiPSC-CMs. a Cell Counting Kit 8 (CCK-8) and b, c trypan blue exclusion assay were used to determine the cell viability, and d LDH leakage and the level of e CK-MB and f CTnI were used to determine cell damage and cytotoxicity. Data are presented as the mean ± SEM, n ≥ 3. *P > 0.05, **P > 0.01, and ***P > 0.001 vs the control group
