Abstract: | The induction of chromosome aberrations in mouse spermatogonia and bone marrow cells by treatment with Mitomycin (MC) was tested. The following dosages were used: 3.5; 1.75; 0.35; and 0.035 mg/kg body weight. Chromatid interchanges and terminal deletions were induced in both tissues. Regarding the chromosome damage, spermatogonia seemed to be more sensitive to the test substance than bone marrow cells.The aberrations observed were considered to represent the cause of dominant lethals induced in spermatocytes after treatment with MC by others. The squash technique adapted for examination of mitoses of mouse spermatogonia proved to be a useful tool in testing potential chemical mutagens. |
