Figure 1.
IR temporarily eliminates the mitotic cell population.
Notes: GL261 cells were exposed to 6 Gy of IR, and the proportion of MPM2-positive cells was quantified by immunofluorescence as described in the “Immunofluorescence” section. MPM2 was utilized as a marker of the mitotic index. Data are expressed as the average ± SEM of three independent experiments.
Abbreviations: IR, ionizing radiation; SEM, standard error of the mean.
