Figure 3.
Expression of Pax3 and Zic1 at the NPB. (A) Developmental expression of Pax3 and Zic1 at the NPB in stage-matched embryos (the stages are indicated in the top right corner). Dorsal views, anterior to top. (B) Transverse section through neurula stage embryos illustrating the relative position of Pax3 and Zic1 in the deeper layer of the ectoderm (arrowheads). Pax3 is also detected in the superficial layer of the ectoderm (arrows), and Zic1 expression domain expands more laterally (bracket) than Pax3. (C) Schematic representation of cross-sections through neurula stage embryo showing the domain of expression of the Pax3 and Zic1 (purple). (D) Xhe and Pax3 are coexpressed in the HG at the tailbud stage. Frontal views. |
