FIGURE 5

Light microscopy of the human OC and lateral wall at the frequency region 500-1000 Hz and confocal microscopy of GJB2. (A) The semi-thin section shows the stria vascularis and the spiral ligament with five different types of fibrocytes (I-V). Basal cells face the type I fibrocytes. The spiral prominence epithelium is thin and changes into a light epithelium in the outer sulcus (OS). (B) A large number of GJB2 gene transcripts are concentrated in the basal cell region. There are no transcripts in the marginal cells. (C) There are few transcripts in the spiral prominence epithelium. A large number of transcripts are seen in the outer sulcus.
