Abstract
A method is provided for producing renal organoids comprising nephrons, ureteric bud and vasculature and/or progenitors of these. In one embodiment, the methods includes contacting intermediate mesoderm cells with: fibroblast growth factor 9 and/or fibroblast growth factor 20 and/or fibroblast growth factor 2 and optionally, one or more selected from the group consisting of: bone morphogenic protein 7; heparin; a Wnt agonist; retinoic acid; and an RA antagonist under conditions that promote formation of vascularized renal organoids. Another embodiment includes producing mesoderm cells by sequentially contacting pluripotent stem cells with a Wnt agonist and fibroblast growth factor 9 and/or fibroblast growth factor 20 and/or fibroblast growth factor 2, followed by a relatively short re-exposure to the Wnt agonist. The renal organoids may have end uses such as for kidney repair and regeneration, bioprinting of kidneys or functional components thereof, renal cell arrays and screening compounds for nephrotoxicity.
