Fig. 2. Normal morphology and prestin expression in hair cells of TrkB-mutant mice. (A) Representative micrographs (DIC) showing the organ of Corti of adult control TrkB^shc/+ and TrkB^shc/- mutant mice. The inner (IHC) and outer hair cells (OHC) are indicated by arrows. (B) Sections were stained with anti-prestin antibodies. No significant differences were noted between either the intensity or expression pattern of prestin in OHCs of TrkB^shc/+ and TrkB^shc/- mice. Scale bars: 20 µm.
