Fig. 3 zfIsl-3 mRNA expression in the body of a 19-hr embryo. (A) A photomontaged lateral view. Anterior, left; dorsal, up. (B) A cryostat cross section made at the rostrocaudal level indicated by the arrow in A. S, spinal cord; N, notochord. zfIsl-3 mRNA was expressed intensely in the ventral myotomes [brackets] and the Rohon-Beard neurons (RB) and weakly in the ventromedial regions (arrowheads) of the dorsal myotomes. Bar, 100 μm (A) and 25 μm (B).
