Figure 5. CESCs repair DNA damage more efficiently than CBCs.
(A) Representative images of γ-H2AX immunofluorescence staining of intestinal sections in control and irradiated mice at 1h, 6h, and 12h after 19 Gy. Scale bar-10 µm. White arrow indicate ISCs. (B) Quantitative analysis of γ-H2AX focus resolution in CBCs and CESCs cells after 19 Gy WBR. Percent ISCs with γ-H2AX foci was determined by counting CBCs located between lysozyme positive Paneth cells and CESCs located between cKit+ positive Paneth-like cells. Data (mean ± standard error) are collated from 3 experiments analyzing 50 ISCs/mouse and two mice/experiment. **p<0.01, *p<0.05.
