Fig 1: Has1 expression in adult mouse cochlea. (A) Has1 expression was more confined within the stria vascularis (SV) in 7-week-old mice. (B) Magnified view of the organ of Corti in (A). The expression in hair cells was weaker than in the SV. Hensen’s and Claudius cells showed similarly weak expression of Has1. (C) Magnified view of the SV in (A). Has1 was robustly localized in the apical membrane of SV marginal cells. (D) Magnified image of the Rosenthal canal. Has1 was detected in some spiral ganglion cells. ICAM2, intercellular adhesion molecule 2; DAPI, 4',6-diamidino-2-phenylindole; OHC, outer hair cell; IHC, inner hair cell. Scale bar: 100 µm.
