Conditional senescence in SVts8 cells. (A) Representative images of SVts8 cells at the permissive (34°C) and non-permissive (39°C) temperatures, stained with DAPI or for SA-βgal activity, CCND1, CDK4 and γH2AX as indicated. (B) Cell size measurements of SVts8 cells grown at 34°C or switched to 39°C for 5 days. (C) Cell cycle profiles of SVts8 cells grown at 34°C or switched to 39°C for 5 days. The percentage of cells in the G1, S, and G2/M phases and with a >4N DNA content are indicated in each panel.
