Fig. 9From: 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 ROS formation in hiPSC-CMs. After treatment with matrine, oxymatrine, cytisine, and sophocarpine, a the images of ROS fluorescence and bright field were acquired intuitively using IncuCyte™ S3 ZOOM cell imaging system and b, c the fluorescence intensity was analyzed quantitatively using TissueQuest 6.0. 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
