FM1-43 uptake experiments. (A–H) Representative images showing dye uptake assessed at 2 dpf (A–D) and 3 dpf (E–H) larvae. (A and E) Control. (B and F) Clarin-1 (Clrn1) MOs. (C and G) MOs + cRNA. (D and H) MOs + cRNAΔCT. Hair cell bundle was counterstained with phalloidin (green). Bar, 7 µm. (I) Semiquantitative analysis of the total fluorescence per neuromast. (J) Number of hair cells per neuromast. (K) Fraction of FM1-43–positive hair cells. Results are expressed as means ± SEM. Number of neuromasts analyzed from independent samples, n > 15. *, P < 0.05; **, P < 0.01; ***, P < 0.001 versus control MO. ++, P < 0.01; +++, P < 0.001 versus clarin-1 MO + cRNA. a.u., arbitrary unit.
