FIG. 5.

Cell cycle analysis of HCMV-infected human primary fibroblasts. (A) Subconfluent, cycling cells were either mock infected or infected with HCMV or UV-irradiated HCMV. Cells in the lower panels were additionally treated with nocodazole (+Noco) 8 h postinfection. (B) Cells were serum starved for 72 h prior to infection. At the time of infection, cells were refed with serum and harvested at the indicated time points after infection, and cultures were then analyzed for cell cycle distribution.
