slc4a2b knockdown leads to decreased lateral line neuromasts in zebrafish. Zebrafish larvae at 72 hpf and the eya1 RNA probe were used in the WISH analysis. (A, B) slc4a2b-morphants (MO) (B) had fewer neuromasts (indicated by red arrows) compared to the controls (A). (C) Quantification of the number of the posterior lateral line neuromasts in slc4a2b-morphants and controls. ***P < 0.001.
