Expression of nos1 during zebrafish development. At 24 hpf, nos1 expression appeared in pallial and subpallial telencephalic territories, in the alar hypothalamus, and in epidermis (A,B). At 48 hpf, nos1 signal emerged in the telencephalon, in the dorsal portion of the hypothalamus, the basal plate of prosomeres 1 to 3, and in the midbrain and rhombencephalon (C,D). At 72 hpf, the olfactory bulbs, the pallium in the telencephalon, the basal plate of prosomeres p1-p3, and the midbrain, cerebellum and rhombencephalon were positively marked (E,F). At 96 hpf, nos1 transcripts were detected in the telencephalon, hypothalamus, diencephalon proper, midbrain, cerebellum, rhombencephalon, eye, and gut (G,H). Abbreviations: ah, alar hypothalamus; c, cerebellum; d, diencephalon; e, eye; g, gut; h, hypothalamus; ha, alar hypothalamus; p1/p3/m, basal plate of prosomere 1 to 3 and midbrain; ep, epidermis; lc, locus coeruleus; ob, olfactory bulbs; r, rhombencephalon; t, telencephalon. DV dorsal view; VV, ventral view; LV, lateral view. Scale bar: 500 µm.
