Effects of tritiated thymidine on cell population kinetics

This paper reports growth-kinetic data of Chinese Hamster tissue culture cells exposed at various times to differnt activities (0.05 muCi/ml up to 10.0 muCi/ml of tritiated thymidine. The analysis of the results aims at the determination of colony-size distribution and to the cellular capacity of reproduction after treatment which is reflected in the cell division spectrum within dialy intervals. The results of the growth-curves represented were converted into integrated curves of colony-size distribution, and their alteration as exponential curves for estimation of the cell cycle as a function of culture time was established. The recovery process and course determination of population kinetics following the 3H-TdR-treatments were evaluated.
