Caption Scanning electron micrographs of cochlear sensory epithelium from Myo7a mutant strains at 8 weeks old. (A-C) Wild-type (Myo7a+/+), (D-F) Myo7aewaso/Myo7aewaso (Myo7aI487N/I487N) and (G-I) Myo7admbo2/Myo7admbo2 (Myo7aF947I/F947I) mice at the apical, middle and basal cochlear level. Signs of degeneration and/or misorientation of outer hair cell (OHC) bundles is evident in both Myo7aewaso/Myo7aewaso (D-F) and Myo7admbo2/Myo7admbo2 (G-I) mice at all levels of the cochlea. This appears to be more severe in Myo7aewaso/Myo7aewaso mutants, where many bundles are missing in the mid and basal regions (E and F). Inner hair cell (IHC) bundles are also affected, appearing disorganised and/or showing signs of fusion in the basal levels of Myo7aewaso/Myo7aewaso cochleae (asterisk in F), and conversely in the apical region of Myo7admbo2/Myo7admbo2 mutants (asterisk in G). Scale bar: 10 um (A-I).
