The expression of a DNA damage marker shows a slightly increasing trend in CDCs from older patients.
(a) CDCs were classified by number of gH2AX foci per nucleus. Representative images of each CDC are shown. (b) The frequencies of gH2AX foci in CDCs are indicated. (c) The frequency of gH2AX-positive (gH2AX+) cells in Ki67-negative (Ki67-) cells in patient-derived CDCs. Arrow indicates representative gH2AX+ /Ki67− cell. Scale bar shows 20 mm.
