Figure 3: Expression of KIAA1199 in the organ of Corti. (a) KIAA1199 expression is observed in the organ of Corti. (b) KIAA1199 expression is observed in MYOSIN7a-positive hair cells and supporting cells between the outer and inner sulcus cells, including SOX2-positive supporting cells. (c) Whole-mount immunofluorescence also showed broad expressions of KIAA1199 in the organ of Corti. ISC: inner sulcus cells, OSC: outer sulcus cells, IHC: inner hair cells, and OHC: outer hair cells. The nuclei were counterstained with Hoechst (blue). Scale bar: (a) and (b): 100 μm, (c): 50 μm.
