GSK-J4 impaired hair cell regeneration after neomycin damage. (A–D) GSK-J4 reduced the numbers of GFP-positive (green) and FM1-43FX-positive (red) hair cells compared with DMSO-treated controls. Scale bars = 10 μm. (E,F) Quantitative analysis of the number of GFP-positive (E) or FM1-43FX-positive (F) hair cells per neuromast (NM) at different time points in DMSO-treated control and GSK-J4-treated larvae. In the 24-h group, n = 40 neuromasts (20 larvae) per group; in the 48-h group, n = 28 neuromasts (14 larvae) per group. ***p < 0.0001. Bars are mean ± sem. [24-h group: One-way ANOVA; GFP-positive cells: F(2, 117) = 96.94; FM1-43FX-positive cells: F(2, 117) = 114. 48-h group: One-way ANOVA; GFP-positive cells: F(2, 81) = 88.96; FM1-43FX-positive cells: F(2, 81) = 93.85].
