Using Wnt-beta catenin reporter mice, we identify a novel Wnt-responsive resident cell population, located in a Frizzled7 expression domain at the surface of the embryonic FB, along the trajectory of incoming ORN axons. Organotypic slice cultures that recapitulate olfactory-associated Wnt-beta catenin activation show that the beta catenin response depends on a placode-derived signal(s). Likewise, in Dlx5-/-embryos, in which the primary connections fail to form, Wnt-beta catenin response on the surface of the FB is strongly reduced. The olfactory placode expresses a number of beta catenin-activating Wnt genes, and the Frizzled7 receptor transduces the "canonical" Wnt signal; using Wnt expression plasmids we show that Wnt5a and Wnt7b are sufficient to rescue beta catenin activation in the absence of incoming axons. Finally, blocking the canonical Wnt pathway with the exogenous application of the antagonists Dikkopf-1 or secreted-Frizzled-receptor protein-2 prevents ORN axon contact to the FB. These data reveal a novel function for Wnt signaling in the establishment of periphery-CNS olfactory connections and highlight a complex interplay between cells of different embryonic origin for ORN axon connectivity."xsd:string |
