Isolation and culture of neonatal mouse cardiomyocytes.

چکیده
Cultured neonatal cardiomyocytes have long been used to study myofibrillogenesis and myofibrillar functions. Cultured cardiomyocytes allow for easy investigation and manipulation of biochemical pathways, and their effect on the biomechanical properties of spontaneously beating cardiomyocytes. The following 2-day protocol describes the isolation and culture of neonatal mouse cardiomyocytes. We show how to easily dissect hearts from neonates, dissociate the cardiac tissue and enrich cardiomyocytes from the cardiac cell-population. We discuss the usage of different enzyme mixes for cell-dissociation, and their effects on cell-viability. The isolated cardiomyocytes can be subsequently used for a variety of morphological, electrophysiological, biochemical, cell-biological or biomechanical assays. We optimized the protocol for robustness and reproducibility, by using only commercially available solutions and enzyme mixes that show little lot-to-lot variability. We also address common problems associated with the isolation and culture of cardiomyocytes, and offer a variety of options for the optimization of isolation and culture conditions.

Evaluation of Chronotropic Properties of Mouse Embryonic Stem Cells-Derived Cardiomyocytes After Fibroblast Growth Factor Treatment
Purpose: We investigated the effect of (bFGF) (basic-Fibroblast Growth Factor) on the differentiation of divided cardiomyocytes from mouse embryonic stem cells (ES) and their pharmacological properties. Materials and Methods: The mouse embryonic stem cells (Royan B1) were cultured as 800 cells per 20µl of a hanging drop. After two days, ES cells in each drop aggregated to form embryoid bodies ...

To study cellular and molecular events of cardiac protection by metallothionein (MT) from oxidative injury, a primary neonatal cardiomyocyte culture was established from a specific cardiac MT-overexpressing transgenic mouse model. Ventricular cardiomyocytes were isolated from 1- to 3-day-old neonatal mice and cultured in an Eagle's minimum essential medium supplemented with 20% fetal bovine ser...

Background DOX is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. However, its cardiac toxicity limits the clinical usefulness of this drug. Previous reports have shown Corticosteroids induce a cytoprotective effect on cardiomyocytes. Mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for a...
