Figure 1From: Duplicate dmbx1genes regulate progenitor cell cycle and differentiation during zebrafish midbrain and retinal developmentSpatiotemporal expression patterns of dmbx1a and dmbx1b at 72 hpf and 96 hpf. Lateral view, anterior to the left (A, C, I, K); dorsal view, anterior to the top (B, D, J, L). Coronal plastic sections (~1 μm; dorsal to the top) of the retina (E, G, M, O) and midbrain (F, H, N, P) were obtained after whole mount labeling with RNA probes. White dotted line in B and D define the position of the representative coronal plastic section shown in F and H, respectively. White dotted line in J and L define the position of the representative coronal plastic section shown in N and P, respectively. White arrow in B, D, J, L demarcates the rostrolateral region of the hindbrain (where the EG is located), and red arrow demarcates the expression in the medulla oblongata. Black arrows in E, M and O point to the INL (inner nuclear layer). The optic tectum (TeO) is demarcated by dotted lines in F, H, N, P and the region of the tegmentum (T) lies just ventral to the TeO. The position of the lens is denoted in E, G, M, O. hpf, hours post-fertilization.Back to article page
