Fig. 1. Endogenous expression of fzd7 in Xenopus heart and relative to wnt11 and
wnt11-R expression. (A, B): stage 10.5 (mid-gastrula) fzd7 and wnt11 expression
detected at the dorsal side of the embryo and appear complementary in the
presumptive heart region. (C-Cii and D-Di): fzd7 and wnt11-R expression at stage 25.
fzd7 is seen in the heart field and wnt11-R in the anterior endoderm. fzd7 and wnt11-
R expression are complementary in the heart region (Cii, Dii). (E, Ei and F, Fi): stage
29 embryos with fzd7 and wnt11-R expression in the heart field. hf: heart field, ae:
anterior endoderm. Magnification 20x. |
