Movie 5.

A septase-null cell invaded by a tri-lobed cleavage furrow. The cell expressed RFP-α-tubulin (red) and GFP- cortexillin I (green). The furrow entered the cell from the left side (370 s and 415 s frames), and two lobes continued to invade the cortexillin-rich area (820 s to 1341 s frames) until a binucleate portion was cleaved off (1402 s frame).
