Zebrafish beta unit gene expression patterns during early embryogenesis. Whole‐mount in situ hybridization of zebrafish embryos at stages 12hpf (A,E,I,M,Q,U), 24hpf (B,F,J,N,R,V), 48hpf (C,G,K,O,S,W), and 72hpf (D,H,L,P,T,X). Anterior is to the left in all the whole‐mount images, and dorsal is to the top in all transverse sections. Each embryo was imaged laterally and dorsally, respectively. A‐D, Lateral view of gene expression of kcnmb2a. E‐H, Dorsal view of gene expression of kcnmb2a. I‐L, Lateral view of gene expression of kcnm2b. M‐P, Dorsal view of gene expression of kcnm2b. Q‐T. Lateral view of gene expression of kcnmb3. U‐X. Dorsal view of gene expression of kcnmb3. The dashed lines indicate the approximate positions of sections. The letters below or around the dashed lines correspond to the panels. Scale bars are added on the top row of images; 250 μm for whole mount images and 50 μm for tissue sections. e, eye; hb, hindbrain; n, neural tube; nt, notochord; op, optic vesicle; ot, optic tectum; ov, otic vesicle; pf, pectoral fin; ph, pharyngeal arch; so, somite; tb, tailbud
