Figure 3. The expression of Xtcad1 during normal development. Whole-mount in situ hybridizations showing the expression of Xtcad1 at various stages. A: Vegetal view of late blastula stage 9 embryo. B: Dorsal side view of early gastrula stage 10+ embryo. The animal hemisphere is to the top, the dorsal lip is visible as a pigmented line. C: Ventral side view of stage 10+ embryo. D: Vegetal view of gastrula stage 10.5 embryo; dorsal is to the top. E: Vegetal view of gastrula stage 12 embryo; dorsal is to the top. F: Dorsal view of late gastrula/early neurula stage 13 embryo; anterior is to the left. G: Dorsal view of late neurula stage 20 embryo. H: Parasagittal open face view of a stage 20 embryo bisected along the anteroposterior axis; anterior is to the left, dorsal is to the top. I: Lateral view of the posterior region from a stage 30 embryo. J: Lateral view of the tail forming region of a stage 33 embryo. K: Lateral view of a dissected gut from a stage 40 embryo; anterior is to the left. L: Lateral view of dissected gut from stage 42 embryo. bp, position of blastopore; cnh, chordoneural hinge; end, endoderm; mes, mesoderm; nec, neuroenteric canal; nt, neural tube; ntc, notochord; pw, posterior wall of neuroenteric canal; st, stomach |
