Movie 4.

LAR and Lyn11-EGFP co-transfected cell treated with cytochalasin D after washout The inhibitory effects of cytochalasin D were attenuated after washout, and the longest protrusion of the same cell shown in Movie S3 was able to elongate again. Images were acquired every 5 minutes. Green fluorescence signals are of Lyn11-EGFP co-transfected with LAR. Scale bar: 20 μm.
