YAP deletion in HBCs reduces the regeneration of OSNs after OE injury
(A) Double immunostaining of GAP43 (green) and OMP (red) in the OE of 2-month-old YAPf/f and YAPK5-CKO mice at 0, 7, and 14 dpl.
(B and C) Quantitative analysis of the density of GAP43+ (B) or OMP+ (C) cells in the OE of 2-month-old YAPf/f and YAPK5-CKO mice at 0, 3, 7, 14, and 28 dpl (n = 9 sections from 5 mice per group).
(D) Immunostaining of Sox9 (green) in the OE of 2-month-old YAPf/f and YAPK5-CKO mice at 0 and 14 dpl.
(E) Quantitative analysis of the density of Sox9+ cells as shown in (D) (n = 11 sections from 5 mice per group).
(F) Immunostaining of OMP (red) in the OB of 2-month-old YAPf/f and YAPK5-CKO mice at 0, 7, and 14 dpl. EPL, external plexiform layer; GL, glomerular layer.
(G) Quantitative analysis of the percentage of area that showed OMP+ area over granule cell layer (GCL) area as shown in (F) (n = 11 sections from 5 mice per group).
Images of selected regions are shown at higher magnification. Data are mean ± SEM, two-way ANOVA with Bonferroni’s post tests, compared with YAPf/f group; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. Scale bars, 20 μm.
