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 6. The analysis of the IR exposed SA‐βgal positive MSCs at various passages. (A) Representative images of the SA‐β-gal positive cells (marked with arrows - cytoplasm colored in dark blue). Nuclei were counterstained with Hoechst 33342 (bright light blue). (B) Changes in the fraction of the SA‐βgal positive cells depending on the passage number in the control and irradiated MSCs. Mean values derived from at least three independent experiments are shown. Error bars show corresponding SE.
