Myosin dynamics in later stages of wild type and Grh KD wound closure. Notum epithelia expressing Sqh::GFP, labeling myosin. Wild type shown on left and Grh KD shown on the right. Zoomed area in Grh KD notum represents portion limited by dashed white square, showing the cortical collapse of the cells. Movies start 30 mpw. Images were acquired using a spinning disk imaging system (Revolution XD; Andor Technology). Frames were taken every 1 min. Scale bars: 20 μm and 10 μm in zoomed area.
