Abstract

MCa-11 tumor cells in exponential monolayer cultures were pulse/chase-labeled with [3H]thymidine and then regrown in fresh, plateau-fed, or starved medium. We measured the DNA content and autoradiographic labeling of these cells by absorption cytophotometry at intervals of 0, 2, 4, 8, 12, and 24 h to follow the progress through the cell cycle of those cells which had incorporated isotope. We found that for the cells grown in plateau-fed and starved medium the G0/G1, S, and G2 phases of the cell cycle were prolonged when compared to those for cells grown in fresh medium. These results show that, under adverse microenvironmental conditions, the growth of tumor cells can be regulated in all phases of the cell cycle, and that this regulation can include lengthening and even cessation of replicative DNA synthesis.
