Movie 2

Dynamic changes of myosin II during cell extrusion.
The center of an epithelial cell in the MRLC-GFP–overexpressing embryo was directly irradiated with a single pulse of the femtosecond laser (15 nJ/pulse) at time = 0 s. Scale bar: 10 μm. Myosin II accumulated at the membranes of cells surrounding the dying cell at around 120 s, and persisted throughout cell extrusion.
