Fig 9. Scanning electron microscopy of typical stereocilia bundles of inner hair cells in Klhl18 mutant mice in middle and apical turns.

Representative images are shown from (A-D) Klhl18^lowf/lowf homozygotes and (E-H) littermate wildtype mice. (A, E) 3 weeks old mice at the 12 kHz best-frequency region; (B, F) 3 weeks old mice at the 24 kHz best-frequency region; (C, G) 4 weeks old mice at the 12 kHz best-frequency region; (D, H) 4 weeks old mice at the 24 kHz best-frequency region. (A-G) show views from the modiolar side of the bundle, but (H) shows a view from the pillar side to illustrate the normal shape of the tallest row of stereocilia. Scale bar (on panel H) represents 1 μm.
