Effects of CDK4 knockdown on the senescence phenotype. (A) Representative images of SVts8 cells transduced with CDK4 or control shRNA at the permissive (34°C) and non-permissive (39°C) temperatures. Cells were stained with DAPI or for CDK4 as indicated. (B) Cell size measurements of SVts8 cells transduced with CDK4 or control shRNA at 34°C or switched to 39°C for 6 days. (C) Cell cycle profiles of SVts8 cells transduced with CDK4 shRNA or control shRNA at 34°C, or switched to 39°C for 5 days.
