Changes in cytoplasmic and lysosomal enzyme activities in cultured rat heart cells: the relationship to cell differentiation and cell population in culture

S Yagev et al. In Vitro. 1984 Dec.

Abstract

Postnatal rat heart cells in culture enriched with respect to muscle cells were obtained by either high density seeding or by the replating technique. [3H]Thymidine incorporation to DNA and the enzymatic pattern of cytoplasmic and lysosomal enzymes have been studied as a function of the culture's age, of seeding density, and replating. It was shown that replating maintains predominance of myocyte population for at least 2 wk in culture; heavy seeding density allows homogeneous myocyte population for the 1st wk in culture; and the enzyme profile of the culture may serve as an indicator for the type of cell population in culture and its state of differentiation.
