Popis: Depending on the concentration, catecholamines activate various intracellular signaling pathways and can induce apoptosis in cardiac myocytes. Although 5, 5’ , 6, 6’ -tetrachloro-1, 1’ , 3, 3’ -tetraethylbenzimidazolocarbocyanine iodide (JC-1) has been previously used to study mitochondria in intact cardiomyocytes, there have been no reports on the detection of apoptosis in neonatal cardiomyocytes in combination with flow cytometry and confocal microscopy. In our study, neonatal rat cardiomyocytes were exposed to norepinephrine (NE) and isoproterenol (ISO) in concentrations of 1 microM and 10 microM for 48 hours. NE concentrations of 1 microM and 10 microM decreased the number of viable cardiomyocytes by 18% (*p
