GFAP-positive cells in the OB. (a) Representative coronal section of the OB stained with glial fibrillary acidic protein (GFAP), NQO1, and Hoechst. Scale bar, 1 mm. (b) Representative images of the olfactory nerve layer (ONL), glomerular layer (GL), and external plexiform layer (EPL) stained with GFAP, NQO1, and DAPI. White dashed circles indicate glomeruli. Scale bar, 200 μm. (c,e) Areas of GFAP-positive cells in the ONL and GL (n = 3, one-way ANOVA followed by Dunnett’s post hoc test. **p < 0.01, ***p < 0.001). (d,f) Comparison of the normalized values of the density of GFAP-positive cells between NQO1-positive and NQO1-negative regions in the ONL and GL (n = 3, Welch’s t-test).
