Abstract Chinese hamster ovary (CHO) cells were treated with a single dose (10 μg/ml) of cis-diammino-dichloroplatinum (II) (cisplatin) for 1 h and the effect of the drug on the kinetics of proliferation of the cultures was studied. It was found that the drug produces a delay in the proliferation rates of the treated cultures. The induction of micronuclei and binucleated cells (BC) at different times after treatment have also been studied, and the ability of these cells to undergo DNA synthesis (measured as the ability to incorporate [3H]thymidine) is shown. It was found that cisplatin induced a particular type of BC that contains one or more micronuclei rather than a pure population of BC. The results obtained show a possible relationship between micronuclei and BC. The possibility that some of the micronucleated cells evolve in subsequent cell divisions to BC with micronuclei is suggested.
