Reduced number of stereocilia in atp11a mutants. (A) Phalloidin staining of F-actin filaments in the hair cells of the atp11anl1005 zebrafish inner ear at 5 dpf, illustrating significant hair cell loss in the medial crista (MC), posterior crista (PC) and macula (PM), as well as the anterior macula (AM), resulting in an overall decrease in the inner ear. (B) Hair cell quantification for the anterior crista (AC), anterior macular, medial crista, posterior crista and posterior macula demonstrates a reduction in stereocilia in heterozygous and homozygous mutants. Data are mean±s.e.m. with significance testing (*P<0.05, **P<0.01, ***P<0.001) calculated using a one-factor ANOVA with Tukey's post-hoc analysis for multiple comparisons. Wild type, n=17; heterozygous, n=22; homozygous mutant, n=7.
