Abstract
Primary cultures of neonatal rat hearts contain both striated muscle (myocytes) as well as nonmuscle heart cells (NMHC). Although myocytes do not divide in culture, NMHC do increase in number. The growth of NMHC is dependent on the concentration of serum in the media over a range of 1 to 10%. When compared to growth in 10%, cells in 1% serum have a prolonged doubling time and reach a maximum density that is 70% less. Thus, 1% serum which supports normal myocyte development is a useful culture media to also maintain muscle heart cell homogeneity by its failure to support optimum NMHC division.
