  Fig. 2. sall4 is expressed in the neurectoderm. (A) Stage 10 embryo stained for sall4 RNA; dorsovegetal view with the dorsal lip of the blastopore toward the top. (B-D) Dorsal views of neurula stage embryos with anterior toward the top. (E) Sagittal section of stage 10 embryo stained for sall4 expression; animal pole is to the top and dorsal to the right. (F-K) Transverse sections at anterior (F,H,J) or posterior (G,I,K) of embryos stained for sall4 as indicated in B-D. (E-K) 50 μm sections, with (F-K) dorsal uppermost. SNE, sensorial neurectoderm; No, notochord; S, somite; PM, paraxial mesoderm; PSM, presomitic mesoderm.
