Math1-positive nuclei and ectopic hair cells. The schematic of the organ of Corti is oriented similar to the mid-modiolar cross sections in Figure 1, a and d–g, in which medial is on left and lateral is on right. The epithelial regions that exhibit Math1-positive nuclei include the organ of Corti (yellow) and ectopic areas adjacent to the organ of Corti (red). Ectopic new hair cells were identified in the interdental cell, inner sulcus, and Hensen cell regions.
