Fig. 3
More neurons express avtr1a1 at 48 hpf. (A) View of the brain focused dorsally showing avtr1a1+ cells in the base of the epiphysis (II) and the forebrain/tectum boundary (III). Inset shows a higher magnification view of the cluster II avtr1a1+ cells with asterisk denoting the epiphysis and dotted line the midline. Scale: 100 µm for (A-C). (B) Same view focused more ventrally than (A) showing the avtr1a1+ cells at the forebrain/tegmentum boundary (IV) and two rough stripes of cells that cross the midbrain/hindbrain boundary (V and VI). (C) Same view focused even more ventrally showing the anterior forebrain avtr1a1+ cells (I). (D) Lateral view showing the avtr1a1+ cells in the anterior forebrain (I), near the dorsal midline of the forebrain (II), at the forebrain/tectum boundary (III), at the forebrain/tegmentum boundary (IV) and the lateral stripe near the midbrain/hindbrain boundary (VI). Outside the brain the pharyngeal arches (arrowhead) and a midline structure in between the eyes (arrow) also express avtr1a1. Scale: 100 µm. (E) View of eye showing avtr1a1+ cells (arrowhead) between the lens and the retina. Scale: 100 µm.
