hearing/vestibular/ear
abnormal scala media morphology ( J:344891 )
• labeling of inner phalangeal cells and border cells indicates a shift in the sensory/nonsensory boundary in the cochlear duct
increased cochlear inner hair cell number ( J:344891 )
• increase in the number of IHC doublets along the length of the epithelium
• increase is seen in the basal, mid, and apical regions, but most pronounced in the apical region
• doublets of IHCs are detectable at E14
