Movie 7

Normal arrangement of actin cytoskeleton associated with migration of control mesendoderm explants: Time-lapse confocal images of a control MO injected mesendoderm explant expressing LifeAct-mCherry. Time interval between each frame is 2 mins and images were collected for 14 mins. Each frame is a collapsed 5um z-stack (Movie is representative of 6 individual explants imaged across 2 separate experiments). Playback rate is 4 frames per second. Scale bar=25um
