FIG. 5. Immunohistochemical localization of DG42 protein in gastrula.
Sections were cut along the dorsal-ventral axis as drawn at the
top and stained with anti-ppAC10 antibodies(only the dorsal region
of the embryo is shown). The antigen is visualized by silver (dark)
deposits. Note that the staining is peripheral to the cells. At this
stage, staining was found in the endoderm and the inner layer of the
ectoderm. In the animal or anterior region( A), the inner layer of the
ectoderm is labeled throughout.In the more posterior section( B), the
region of the ectoderm becoming neural plate is not stained. |
