Web22 mei 2024 · To test for the possibility of a delay in meiosis entry in the absence of RAR (see above), we analyzed at E15.5 control and mutant ovaries of fetuses treated by TAM at E9.5. Virtually, all germ cells had entered meiosis in the mutant ovaries, as attested by the detection of SYCP3 in almost all germ cells (Fig. 6, A and B). WebThe results demonstrate that the time of chemical treatment influences the frequency of aneuploidy and the degree of meiotic delay and emphasize that to thoroughly characterize the aneugenic potential of a specific chemical several treatment times may be needed.
