Dorsal EFG-induced actin dynamics in control A431 cells. Control siRNA-transfected, GFP-actin–expressing A431 cells were analyzed by time-lapse epifluorescence microscopy (Axiovert 200M). The focal plane was set to the dorsal level. Images were taken every 5 s for 10 min and 35 s (frame rate of replay: 15 frames per second).
