Primary Culture of Adult Rat Heart Myocytes
Cultured primary adult rodent heart cells are an important model system for cardiovascular research. Nevertheless, establishment of robust, viable cultured adult myocytes can be a technically challenging, rate-limiting step for many researchers. Here we described a protocol to obtain a high yield of adult rat heart myocytes that remain viable in culture for several days. The heart is isolated a...
متن کاملTransformation of adult rat cardiac myocytes in primary culture.
We characterized the morphological, electrical and mechanical alterations of cardiomyocytes in long-term cell culture. Morphometric parameters, sarcomere length, T-tubule density, cell capacitance, L-type calcium current (I(Ca,L)), inward rectifier potassium current (I(K1)), cytosolic calcium transients, action potential and contractile parameters of adult rat ventricular myocytes were determin...
متن کاملDifferentiation of adult rat cardiac myocytes in cell culture.
Cardiac myocytes isolated from adult rat hearts were grown on laminin coated culture dishes for more than a month. During this time, the cells underwent a morphological transformation which has also been referred to by others as cell remodeling (Guo J-X, Jacobson SL, Brown DL: Cell Mot Cytoskeleton 1986;6:291-304). This results in a change in myocyte morphology from its typical in vivo cylindri...
متن کاملRelease of enzymes from adult rat heart myocytes.
The release of lactic dehydrogenase, creatine phosphokinase, and aspartate aminotransferase from initially viable, metabolically competent adult rat heart myocytes has been examined. Freshly isolated cells contain levels of total lactic dehydrogenase, creatine phosphokinase, and aspartate aminotransferase, as well as lactic dehydrogenase and creatine phosphokinase isoenzyme profiles that are qu...
متن کاملAcidic and basic fibroblast growth factors in adult rat heart myocytes. Localization, regulation in culture, and effects on DNA synthesis.
Basic fibroblast growth factor (bFGF) and acidic fibroblast growth factor (aFGF) are involved in the induction of embryonic mesoderm, angiogenesis, neuronal differentiation, and proliferation and survival of many cell types. In cardiac myocytes their roles are not well understood. Effects of fibroblast growth factors on reexpression of fetal actin genes have been reported. In freshly isolated a...
