Cropped image from a low resolution (10X) long term light-sheet movie that shows how we quantified apical extrusion (arrow frame 15) and basal extrusion (arrowhead frame 81). Movie is 100 frames with images taken every 3 minutes. Scale is 20μm. Bidirectional multiciliated cell extrusion is controlled by Notch-driven basal extrusion and Piezo1-driven apical extrusion Rosa Ventrella, Sun K.
