The generation of ureteric bud (UB), which is the renal progenitor that gives rise to renal collecting ducts and lower urinary tract, from human-induced pluripotent stem cells (hiPSCs) provides a cell source for studying the development of UB and kidney disease. Here we describe a stepwise and efficient two-dimensional differentiation method of hiPSCs into Wolffian duct (WD) cells. We also describe how to generate three-dimensional WD epithelial structures that can differentiate into UB-like structures.
