Human pluripotent stem cells (hPSC) are investigated as a source of authentic human cardiac cells for drug discovery and toxicological tests. Cell-based assays using automated fluorescence imaging platform and high-content analysis characterize hypertrophic and toxicity profiles of compounds in hPSC-derived cardiomyocytes (hPSC-CM) at the cellular and subcellular levels. In purified population of hPSC-CM loaded with cell tracer probe and cell death markers, both hypertrophic and toxicity profiles can be assessed in live cardiomyocyte cultures. Alternatively, in non-purified cultures of hPSC-CM, hypertrophy, proliferation, and cell death assays can be performed specifically in the cardiomyocyte subpopulation using antibodies directed against cardiac proteins and a combination of cell death- and proliferation-specific fluorescent probes.
