Mutations specifically affecting hair cell regeneration. a A fluorescent image of a zebrafish embryo at 5 dpf stained with Yopro-1, showing the distribution of neuromast hair cells. Arrows point to the P1–P4 neuromasts that were used for hair cell counting. b A magnified image of neuromast hair cells in the P1 neuromast. c–g Quantification of impaired hair cell regeneration caused by rnpc3^la028632 retroviral insertional mutation (c), hspe1^hg77 (6 bp CRISPR deletion) mutation (d), hspa13^hg78 (12 bp CRISPR deletion) mutation (e), smn1^fh299 (ENU missense Y262X) mutation (f), and gemin5^hg80(1 bp CRISPR deletion) mutation (g). The graphs are obtained from analyzing and then genotyping ~45 embryos generated from a pairwise incross of heterozygotes. Graphs show the mean and s.e.m. The difference between the wild-types and homozygotes is significant for all mutations (p < 0.05)
