Immunohistochemical localization of Osbpl2 in a 12-week-old C57BL/6 mouse cochlea. (a) Low magnification of the mouse cochlea. Osbpl2 was strongly expressed in the stria vascularis (SV), spiral ganglion (SG), inner hair cells (IHCs), and outer hair cells (OHCs). Osbpl2 was also detected in the spiral ligament (SL). The scale bar represents 100 μm. (b) High magnification of the SG, showing intensive staining of some positive cells. The scale bar represents 20 μm. Osbpl2, oxysterol binding protein-like 2.
