Early developmental expression pattern of the zebrafish nelf by whole-mount in situ hybridization. Subfigures in the right panel are enlargements of the boxed areas in the central panel. Dashed lines depict the forebrain edge. A-C: At 24 hours postfertilization (hpf); D-F: At 32 hpf; G-I: At 48 hpf. nelf is expressed in the olfactory bulb and in the olfactory bulb-olfactory epithelium boundary (white arrows in F and I). J-L: At 72 hpf, nelf is no longer expressed in the olfactory epithelium (L). Ep, epiphysis; H, hypothalamus; Hb, hindbrain; M, midbrain tegmentum; OB, olfactory bulb; Olf, olfactory epithelium; Tel, telencephalon; R, retina. Lateral (left column) and dorsal (central and right panels) views, anterior is left. Scale bar = 100 μM in left and central panels; 50 μM in right panel.
