Control cells treated with nocodazole arrest in mitosis with condensed chromatin. BE cells transfected with negative siRNA were treated with 3.32 µM nocodazole and analyzed by phase-contrast time-lapse microscopy. Time = 0, NEBD. Frames were taken every 20 min for 800 min. Time counter shows minute:second. Display rate: one frame per second. Related image stills are shown in Fig. 5 B.
