Abstract

The formation of the apical ectodermal ridge (AER) is critical for the distal outgrowth and patterning of the vertebrate limb. Recent work in the chick has demonstrated that interplay between the Wnt and Fgf signaling pathways is essential in the limb mesenchyme and ectoderm in the establishment and perhaps the maintenance of the AER. In the mouse, whereas a role for Fgfs for AER establishment and function has been clearly demonstrated, the role of Wnt/β-catenin signaling, although known to be important, is obscure. In this study, we demonstrate that Wnt3, which is expressed ubiquitously throughout the limb ectoderm, is essential for normal limb development and plays a critical role in the establishment of the AER. We also show that the conditional removal of β-catenin in the ventral ectodermal cells is sufficient to elicit the mutant limb phenotype. In addition, removing β-catenin after the induction of the ridge results in the disappearance of the AER, demonstrating the requirement for continued β-catenin signaling for the maintenance of this structure. Finally, we demonstrate that Wnt/β-catenin signaling lies upstream of the Bmp signaling pathway in establishment of the AER and regulation of the dorsoventral polarity of the limb.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
