Figure 2: γ-H2Ax labeling in scala media. Panel A shows that several structures are labeled but the most prominent is the organ of Corti. γ-H2Ax labeling can be detected in the organ of Corti with (panel C) and without (panel B) noise exposure. The labeling is predominantly localized in hair cells and supporting cells. Abbreviations: Oc, organ of Corti; Ohc, outer hair cell; Ihc, inner hair cell. The scale bar in panel A is 100 μm and the scale bars in panels B and C are 10 μm.
