A survey of intracellular Na+ and K+ of various normal, transformed, and tumor cells.
Intracellular concentrations of Na+ and K+ of various normal, transformed, and tumor cell cultures were analyzed by atomic absorption spectrophotometry. In all of the cultures analyzed there were markedly different concentrations in the transformed and tumor cells when compared to their normal counterparts. Although increased Na+ was often observed, there were no definitive correlations between absolute ion concentrations, or Na+:K+ ratios, and cell transformation.
