dtx1 expression in developing zebrafish. dtx1 expression was detected using in situ hybridization in the developing nervous system during zebrafish embryogenesis. The embryo stages are shown in the bottom right corner of each panel. a Lateral view with anterior to the right. b–e Dorsal view with anterior to the top. b–f dtx1 expression occurred first in the developing nervous system during the bud stage (b) and remained until the final stage that was analyzed (e) Arrows in c and d indicate dtx1 expressing cells flanking the midline. E, eye; FB, forebrain; HB, hindbrain; MB, midbrain; MHB, midbrain-hindbrain boundary; SC, spinal cord
