Figure 2. Developmental expression of znf703. (a–d) By in situ hybridization at the neurula stage (NF stage 13/14) znf703 is detected in the dorso-lateral ectoderm posteriorly, including the neural plate and the neural crest forming region, with a gap of expression at the dorsal midline. (e and f) At stages 16 through 19, znf703 expression persists in the dorsal ectoderm where it appears to be confined to the prospective hindbrain and spinal cord. (g) Transverse section of a stage 16 embryo, dorsal to top, showing znf703 expression in the neural plate (np), neural crest (nc), ventral non-neural ectoderm (nne) and lateral plate mesoderm (lpm). (k–m) Later in development znf703 is diffusely expressed throughout the ectoderm, and enriched in the hatching gland (hg) and the branchial arches (ba). (a, c, e, h, and k) dorsal views, anterior to top. (b, d, j, l, and m) lateral views, dorsal to top, anterior to right. (f, and i) frontal views, dorsal to top. The embryonic stages are indicated in the lower left corner of each panel |
