Figure 5. Expression of Xnot along the dorsal midline. Embryos were processed for whole-mount in situ hybridization and embedded in paraffin, and transverse sections were cut. (A) Section through the middle of a stage 12.5 (late gastrula) embryo. Staining is observed only at the dorsal midline in all three germ layers. The archenteron was slightly deformed during sectioning. (B) Posterior section of a stage 16 (neural plate stage) embryo. Xnot expression is observed along the dorsal midline in the notochord (n), archenteron roof (a), and in the floor plate (f) of the neural tube. (C) Posterior section of a stage 18 (neural fold stage) embryo. The same regions expressed Xnot as in B. Dorsal is at the top of each section. Image published in: von Dassow G et al.
