Movie 4.

Periodic actin waves drive non-directed fat body cell swimming migration – Related to Fig. 2A. Confocal movie of actin dynamics in migrating FBCs expressing Lsp2-Gal4+UAS-LifeAct- GFP. Red arrowheads point at consecutive actin waves in the rear of a migrating FBC. Elapsed time shown in top left corner in minutes:seconds. Scale bar, 20 μm.
