| FIG. 4. Wraps were prepared as usual and examined for expression of the extremely anterior XAG-1 gene. (A) A tadpole at stage 25 expresses XAG-1 in the cement gland (arrowhead); (B) isolated animal caps rarely express the gene autonomously; (C) whole organizers and (D) anterior organizers both strongly induce XAG-1; and (E) posterior organizers induce less XAG-1. |
