Table 2.

The number of hair cells in the sensory macula and cristae of wild-type zebrafish and atp2b1a morphants at 4 dpf

Anterior maculaAnterior cristaePosterior cristaeLateral cristae
Wild-type fish (N=7) 32.1±7.5 6.7±1.5 7.3±1.0 7.4±1.7 
atp2b1a morphant (N=13) 13.8±3.2 2.8±1.3 3.0±1.2 1.8±1.3

Wild-type fish (N=7) 32.1±7.5 6.7±1.5 7.3±1.0 7.4±1.7 
atp2b1a morphant (N=13) 13.8±3.2 2.8±1.3 3.0±1.2 1.8±1.3 

Values are mean ± standard deviation; N=sample size. After HCS-1 antibody and FITC-phalloidin staining, the hair cells were counted from the dorsal view under the confocal microscope. The hair cells in the posterior macula appear overlapped from the dorsal view and so were not counted. Statistical analysis suggests significantly fewer hair cells in atp2b1a morphants than in the wild-type zebrafish for each corresponding tissue
