Abstract: An exemplary method can be provided for producing ureteric bud cells from pluripotent stem cells, in vitro. Further, an exemplary method can be provided for producing ureteric bud cells and Wolffian duct (WD) progenitor-like cells that are a progenitor of the ureteric bud cells. Another exemplary method can be provided for producing Wolffian duct (WD) progenitor-like cells that can comprise obtaining C-X-C chemokine receptor 4 (CXCR4) positive and KIT proto-oncogene receptor tyrosine kinase (KIT) positive cells. In addition, an exemplary method can be provided for producing ureteric-bud-like cells using WD progenitors that are CXCR4+ and KIT+, and another exemplary method can be provided for producing kidney organoids in which the ureteric-bud-like cells can be used.

Abstract: The purpose of the present invention is to provide a process or method that can be utilized when deriving a three-dimensional structure of a kidney from pluripotent stem cells such as ES cells or iPS cells. The differentiation inducing method is characterized by culturing pluripotent cells with the following three steps, in order: (a) a step of culturing an embryoid body induced from the pluripotent stem cells in medium containing Bmp4 and a high-concentration (concentration A) Wnt agonist; (b) a step of culturing the embryoid body in medium which contains activin, Bmp4, retinoic acid and a middle-concentration (concentration B) Wnt agonist; and (c) a step of culturing the embryoid body in medium containing Fgf9 and a low-concentration (concentration C) Wnt agonist (herein, the Wnt agonist concentrations is concentration A>concentration B>concentration C).
