'This protocol describes how to isolate primary cardiomyocytes from adult zebrafish hearts and culture them for up to 4 weeks, thereby using them as an alternative to in vivo experiments. After collagenase digestion of the ventricle, cells are exposed to increasing calcium concentrations in order to obtain high-purity cardiomyocytes. The ... More

'beta(1) and beta(2) adrenergic receptors (AR) regulate the intrinsic contraction rate in neonatal mouse cardiac myocytes through distinct signaling pathways. It has been shown that stimulation of beta(1)ARs leads to a protein kinase A-dependent increase in contraction rate. In contrast, stimulation of beta(2)ARs has a biphasic effect on contraction rate, ... More
