gH2AX focus formation and loss in BL-treated Syrian hamster fibroblasts. Bar chart representing gH2AX focus counts per nucleus in G0 fibroblasts of early (passage 1) and late (passage 5) passages. 200 cells were analyzed for each time point, and the average numbers of foci per nucleus ±SE are shown. The differences between average numbers of foci per nucleus in early- and late-passage cells are statistically significant (p < 0.01) for the time points 4, 24, 48, 72 h. “C” indicates the charts for gH2AX focus counts in non-treated (control) cells
