- Appl. No: 16/682541
- Application Filed: November 13, 2019
- نبذة مختصرة : 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.

- Claim: 1. A method of producing one or more renal organoids comprising: (a) differentiating intermediate mesoderm (IM) cells into nephron progenitor cells and ureteric epithelial progenitor cells by contacting the IM cells with a Wnt agonist, fibroblast growth factor 9 (FGF9), and one or more compounds selected from the group consisting of bone morphogenic protein 7 (BMP7), heparin, retinoic acid (RA), an RA analog, an RA agonist, and an RA antagonist, wherein the RA antagonist increases the relative production of nephron progenitor cells from the IM cells; and (b) culturing the nephron progenitor cells and ureteric epithelial progenitor cells under conditions that induce aggregation of the nephron progenitor cells and ureteric epithelial progenitor cells into one or more renal organoids that are at least partly vascularized and/or comprise vascular progenitors, wherein the vascularization is facilitated by conditions that promote or direct development of vascular endothelium or vascular progenitors from mesenchymal cells or tissues.
