Figure 1. Evolution of X-Delta-2 anterior neural expression. A-G: Albino embryos from stage 14 (A) to 22 (G) shown from the anterior side with dorsal to the top. H-J: Lateral view of stage 25, 27, and 36 albino embryos; anterior to the left. The first appearance of X-Delta-2 expression in a certain region is marked in the figure, except in G and H, where all the regions are marked. Arrowheads in A indicate X-Delta-2 expression in the neural plate border, and the arrow indicates the basal plate border. Arrows in B indicate the expression in the neural tube. The arrow in H indicates the otic vesicle. Arrowheads in K indicate forebrain-midbrain and midbrain-hindbrain boundary. Arrows in L indicate the X-Delta-2 expression in the middle of the hindbrain. In M, white arrows indicate the expression in the forebrain, black arrows in the tectum of the midbrain, and the arrowheads the expression in the hindbrain. The dotted line in M represents the level of the cut shown in N. Arrowheads in N mark the rhombomere boundaries. Dorsal and ventral are shown by the arrow.
