Figure 4. Comparison of the expression domain of Xhairy2b with that of anterior endodermal genes and chordamesodermal genes at the early gastrula stage. A: Neighboring sections in the mid-sagittal plane of stage 10.5 embryos. Dorsal is to the right. Arrowheads indicate the blastopore lip. B,D,F:Xhairy2b is expressed in the ectoderm and the deep layer of the dorsal blastopore lip at the early gastrula stage. A,C: The expression of Xhex (A) and Xdkk1 (C) in the anterior endoderm is hardly overlapped with the expression of Xhairy2b. E: The expression of chordin in the deep layer of the organizer is overlapped with that of Xhairy2b.
