Fig. 10From: 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 analyzed 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 the control groupBack to article page
