Residual γH2AX foci induced by low dose x-ray radiation in bone marrow mesenchymal stem cells do not cause accelerated senescence in the progeny of irradiated cells


Figure 3. Comparative immunocytochemical analysis of γH2AX foci in resting (Ki67‐) and proliferating (Ki67+) cells. (A) Representative microphotographs of the immunofluorescently stained irradiated MSCs showing Ki67 (green) and γH2AX foci (red). DAPI nuclear counterstaining is shown in blue. (B) Comparative changes in the foci number in resting vs proliferating cells exposed to the low vs. intermediate dose of X-ray radiation. Mean values derived at least from three independent experiments are shown. Error bars show SE.
