FIG. 7.
Vestibular hair cells of Myo15 and Whrn single and double mutants exhibit cytocaud pathology at birth. Epifluorescence images of whole mounts of the ampulla of P21 control mice (a), single mutants of Myo15 (b) and Whrn (c), and Myo15, Whrn double mutants (d) labeled with phalloidin. At the focal plane just beneath the cuticular plate, an actin-positive stain is detected in most of the vestibular hair cells of Myo15 (b) and Whrn (c) single mutants and Myo15, Whrn (d) double mutants (arrows), but not in control mice.
