Cover legend: Confocal image of the utricular sensory epithelium from a postnatal day 6 (P6) mouse in which expression of eYFP (green) was induced specifically in hair cells on P0 and P1. Antibody labeling of the hair cell-specific protein myosin VIIA is shown in purple. The sensory epithelium has been segmented with an edge detector and overlaid on a black background. For more information, see the article by Burns et al. (pages 6570–6577).
