Wound closure dynamics in control, Drp1 mild and Drp1 strong embryos. Embryos express GFP::Moesin that marks F-actin. Images are maximum Z-projections of 55 slices (15.4-μm-thick stack) acquired by time-lapse spinning-disk confocal microscopy every 2 min. The frame rate is five frames/s. Video stills are shown in Fig. 2.
