Figure 2: (a) Frequency of cells containing micronuclei per 1000 binucleated cells of QU-DB and MRC5 bystander cells which received medium from 0.5, 2, and 4 Gy irradiated and sham-irradiated cells. Values represent mean of at least five independent experiments ± SD. *P < 0.005 for each subgroup relative to its control group. (b) Relative MC of QU-DB and MRC5 bystander subgroups. For each dose, relative MC was obtained by dividing the frequency of micronucleated cells in QU-DB and MRC5 bystander subgroups by spontaneous MC of the same cell type
