Movie 2.

Disappearance of actin waves at the onset of mitosis. The cell expressed microtubule (green) and actin (red) markers as the cell in Movie 1. Propagation and extinction of an actin wave is seen in the 0 s to 102 s frames. Entry of an actin-rich protrusion into a cleavage furrow is indicated in the 838 s frame by an arrowhead. This movie is related to Figure 1C.
