Epithelial branching morphogenesis is critical to the formation of various organs such as the vasculature, mammary glands, lungs, and kidneys in vertebrate embryos. One fascinating aspect of branching morphogenesis is to understand how a simple epithelial tube grows by reiterative branching to form a complex epithelial tree structure. Recent studies combining mouse genetics and chimeric analysis with live imaging have uncovered the molecular networks and interactions that govern kidney branching morphogenesis. This review focuses on ureteric bud (UB) formation and epithelial branching during kidney development. The invasion of the metanephric mesenchyme by the UB is a fundamental step toward establishing the cyto-architecture of the kidney and determining the number of nephrons, which form the filtration units of the adult kidney.
