Abstract: | The primary culture of neonatal mice cardiomyocyte model enables researchers to study and understand the morphological, biochemical,
and electrophysiological characteristics of the heart, besides being a valuable tool for pharmacological and toxicological
studies. Because cardiomyocytes do not proliferate after birth, primary myocardial culture is recalcitrant. The present study
describes an improved method for rapid isolation of cardiomyocytes from neonatal mice, as well as the maintenance and propagation
of such cultures for the long term. Immunocytochemical and gene expression data also confirmed the presence of several cardiac
markers in the beating cells during the long-term culture condition used in this protocol. The whole culture process can be
effectively shortened by reducing the enzyme digestion period and the cardiomyocyte enrichment step.
