Wnt7b, expressed by the collecting duct epithelium, regulates the orientation of epithelial cell division planes to establish the cortico-medullary axis of the kidney; in Wnt7b mutants, cell divisions are biased radially instead of longitudinally. Wnt7b acts paracrinally through the canonical Wnt/beta-catenin pathway in the surrounding interstitium, as shown by the fact that removal of beta-catenin from Wnt-responsive interstitium phenocopies the Wnt7b mutant medullary deficiency. |
