Fig. 10From: Correction: An integrated characterization of contractile, electrophysiological and structural cardiotoxicity of Sophora tonkinensis Gapnep. in human pluripotent stem cell-derived cardiomyocytesEffect of matrine, oxymatrine, cytisine and sophocarpine on intracellular calcium in hESC-CMs. After treatment of matrine, oxymatrine, cytisine and sophocarpine, the images of calcium fluorescence and bright field were acquired intuitively and the fluorescence intensity was analysed quantitatively using IncuCyte™ S3 ZOOM cell imaging system. The scale bar is 400 μm. Data are presented as the mean ± SEM, n ≥ 3. *P > 0.05, **P > 0.01 and ***P > 0.001 vs control groupBack to article page
