In testing the hypothesis that the small-colony thymidine kinase-deficient mutants of L5178Y/TK+/- -3.7.2C mouse lymphoma cells represent an estimate of the clastogenicity of test chemicals, we have been performing gross aberration analysis. The present study was initiated to determine if the cytokinesis block method of micronucleus analysis could be performed in mouse lymphoma cells and to compare 3 different endpoints of clastogenicity: the number of metaphases with aberrations, number of binucleates with micronuclei, and small-colony TK mutant frequency. In this study, 12 compounds having varying clastogenic potencies were evaluated. As would be expected, the 3 endpoints vary in the relative magnitude of the quantitated response. This difference likely results from the types of clastogenic damage detected by each endpoint. Of the 3 endpoints tested, only the small-colony TK mutant frequency measures events compatible with long-term cell survival.
