Human cardiac myocytes undergo degeneration, cytolysis, and necrosis in a number of clinical disease conditions such as myocarditis, dilated cardiomyopathy, and during episodes of cardiac allograft rejection. The precise cellular, biochemical, and molecular mechanisms that lead to such abnormalities in myocytes have been difficult to investigate because at present it is not possible to obtain and maintain viable cell cultures of human adult cardiac myocytes in vitro. However, human fetal cardiac myocytes are relatively easy to maintain and culture in vitro, but their limited availability and growth, variability from one preparation to another, and varying degrees of contamination with endothelial and epithelial cell types have made it difficult to obtain reliable data on the effect of cardiotropic viruses and cardiotoxic drugs on such myocytes. These thoughts prompted us to attempt to derive a cell line of human cardiac origin. Highly enriched human fetal cardiac myocytes were transfected with the plasmids pSV2Neo and pRSVTAg and gave rise to a cell line (W1) which has been maintained in culture for 1 yr. Morphologic and phenotypic analyses of W1 cells by flow microfluorometry and immunoperoxidase techniques indicate that the W1 cell line shares many properties of human fetal cardiac myocytes, but appears not to react with specific antibodies known to react with markers unique to human endothelial, epithelial, skeletal muscle, and dendritic cells. These preliminary data suggest that the W1 cells may provide a unique source of an established cell line that shares many properties ascribed to human cardiac myocytes.
