| FIG. 2. (A) Whole-mount in situ hybridizations of gastrula and neurula stage embryos with antisense probe recognizing Xnr4 (panels on the left) and with control Xnr4 sense probe (panels on the right). The gastrula (stage 10) embryo is shown as a vegetal view with the dorsal blastopore lip at the top of the panel and the neurula (stage 19) embryo is shown as a dorsal view with the posterior end at the bottom of the panel. (B) An in situ hybridization of a sagittal section of a gastrula stage embryo showing the expression of Xnr4 in the deep cells of the dorsal blastopore lip. (C) An in situ hybridization of a transverse section of a late neurula stage embryo showing expression of Xnr4 in the notochord and the ventral neural tube. |
