Fig. 3. The spatial pattern of xC/EBPb expression during embryogenesis. Whole-mount in situ hybridisation to digoxigenin-labelled antisense (A) and sense probes (F), derived from the N-terminal region of the xC/EBPb gene, was carried out as described in Section 3. (A) mid-gastrula embryo (stage 11) showing expression around the blastopore lip and in endodermal cells; (B) stage 22 embryo indicating expression in the fore brain and along the whole dorsal side; (C) stage 30 embryo indicating expression in the optic vesicle (ov), branchial arches (b), spinal cord (sc) and somites; (D) close view of a stage 30 embryo showing expression in the somites and the spinal cord; (E) stage 38 embryo, arrow indicates expression in the region that gives rise to the liver and heart; (F) representative control embryos probed with the sense probe, stages 11 (F), 22 (G) and 30 (I). |
