The requirement for primary cilia during renal epithelial-mesenchymal tissue interactions that give rise to nephrons is undefined. Here, we used <i>Cre-</i>mediated recombination to generate mice with <i>Kif3a</i> deficiency targeted to the ureteric and/or metanephric mesenchyme cell lineages in the embryonic kidney. Gradual loss of primary cilia in either lineage leads to a phenotype of reduced nephron number. Remarkably, in addition to cyst formation, loss of primary cilia in the ureteric epithelial cell leads to decreased expression of <i>Wnt11</i> and <i>Ret</i> and reduced ureteric branching. Constitutive expression of GLI3 repressor (<i>Gli3<sup>Δ699/+</sup></i>) rescues these abnormalities. In embryonic metanephric mesenchyme cells, <i>Kif3a</i> deficiency limits survival of nephrogenic progenitor cells and expression of genes required for nephron formation. Together, our data demonstrate that <i>Kif3a</i> controls nephron number via distinct cell lineage-specific mechanisms.</p></div> developmental biology;Molecular development;morphogens;signaling;morphogenesis;Birth defects;Growth control;embryology;Model organisms;Animal models;mouse;Nephrology;Developmental nephrology;controls;murine;nephron;gli3;lineage-specific 2013-06-07
