Fig. 1: The densities of spiral ganglion neurons (SGNs) in the cochleae of Fscn2^−/− mice were gradually decreased.

A SGN densities were detected in Fscn2^+/+ mice and Fscn2^−/− mice by HE staining. B The densitometric analysis was made by ImageJ software. Data are represented as means ± SEM. Scale bar, 50 μm. **P < 0.01.
