title: Differential susceptibility of L cells in the exponential and stationary phases to cadmium chloride.
abstract: Comparative studies of the cellular toxicity and uptake of cadmium in L cells in the exponential and stationary phases were done. The LD50 of cadmium chloride to L cells in the exponential and stationary phases was 5.5 and 30.5 muM respectively and the cadmium content of L cells exposed to 5.4 muM cadmium chloride for 3.5 hr in the exponential and stationary phases was 0.123 and 0.065 mug/10(6) cells, respectively. These results suggest that the higher susceptibility of cells in the exponential phase to cadmium may be caused by an increased permeability of the cell membrane to cadmium.
