Cover picture: Airway surface liquid (ASL) depth measured by surface laser reflectance microscopy (SLRM). (Left) SLRM images of airway surface liquid at three locations in primary human bronchial epithelial cell culture. Dashed white line indicates ASL surface. (Middle) Intensity versus distance profiles. (Right) Confocal fluorescence image showing red-stained airway surface liquid and green-stained epithelium. Fluorescence z-profile and depth number histogram shown below images. Bars, 10 µm (see tutorial research article by Thiagarajah et al., 353–362).
