Fig. 4

The number of hair cells and neurons was significantly decreased by MO-mediated gfi1.2 knockdown and can be rescued by exogenous gfi1.2. Neurons were labeled by the immunostaining of Myo6 and tubulin at 2 dpf. The number of neurons in the zebrafish neuromast was compared in (A) wild-type (wt), (B) MO-mediated gfi1.2-knockdown, (C) gfi1.2 mRNA-overexpressing, and (D) MO gfi1.2 + gfi1.2 mRNA. Hair cells were also labeled by the immunostaining of Myo6 and tubulin at 2 dpf. The number of hair cells in the zebrafish inner ear was compared in (E) wild-type (wt), (F) MO-mediated gfi1.2-knockdown, (G) gfi1.2 mRNA-overexpressing, and (H) MO gfi1.2 + gfi1.2 mRNA. In the gfi1.2 mutants, hair cells in the utricle maculae (UM) and saccule maculae (SM) significantly decreased in number (p < 0.05). Over-expression of gfi1.2 in the wild-type zebrafish did not affect the number of hair cell number (E). NS: not significant. The utricle is indicated by a white *, and the contralateral structure is the saccule.
