Apical and basal actin dynamics in later stages of wild type and Grh KD wound closure. Notum epithelia expressing mCherry::Moesin under the control of pnr-Gal4 driver, labeling F-actin. Wild type shown on left column and Grh KD shown on the right column. Apical (top images) and basal (bottom images) sides of area close to wound edge. Zoomed areas in Grh KD notum represent portions limited by dashed white square, showing cells emitting filopodia (apical) as they round up (basal). Movies start 30 mpw. Images were acquired using a spinning disk imaging system (Revolution XD; Andor Technology). Frames were taken every 5 min. Scale bars: 15 μm and 7 μm in zoomed area.
