Fig. 16 The kcnk18 gene (tandem of pore domains in a weak inward rectifying K+-related spinal cord K+ channel) expression during zebrafish embryogenesis. Whole-mount in situ hybridization of zebrafish embryos at stages 12 h postfertilization (hpf) (A and E), 24 hpf (B and F), 48 hpf (C and G), and 72 hpf (D and H). The anterior is to the left in all the whole-mount images, and the dorsal is to the top in all transverse sections (G2). (A–D) Lateral view of gene expression of kcnk18. (E–H) Dorsal view of gene expression of kcnk18. The white dashed lines indicate the positions of sections. The section images were shown in the insert of corresponding panels. Scale bars were added on the bottom row of images; 250 μm for whole-mount images. allg, anterior lateral line ganglia; e, eye; hb, hindbrain; mb, midbrain; n, neural tube; op, optic vesicles; ov, otic vesicles; pa, pharyngeal arches; rb, Rohon–Beard (RB) neurons; tb, tail bud.
