Cardiomyocyte assays

Stem cell-derived human cardiomyocytes assays

Stem cell-derived human cardiomyocytes have phenotypic characteristics and electrophysiological profiles similar to those of native human cardiac cells. Cardiomyocytes in culture are able to form a beating syncytium, which behaves similarly to native cardiomyocytes. Oscillation of intracellular calcium levels occurring with synchronized contractions of the cells can be monitored using a calcium-sensitive dye, and treatment-induced changes in the pattern of oscillation can be monitored via changes in fluorescent signal over time.
