A developmentally-inspired hypoxia condition promotes kidney organoids differentiation from human pluripotent stem cells

ABSTRACT: Kidney organoids derived from human pluripotent stem cells (hPSCs) lack a contiguous network of collecting ducts, which limits their utility in modeling kidney development and disease. Here, we report the generation of kidney organoids containing ureteric bud (UB)-derived collecting ducts connected to metanephric mesenchyme (MM)-derived nephrons using a developmentally-inspired hypoxic differentiation condition. Hypoxia promotes a reiterative process of branching morphogenesis and nephron induction through reciprocal interactions between co-induced MM and UB, which lead to a higher-order kidney organogenesis in vitro. The resulting kidney organoids demonstrate greater maturity, as indicated by higher levels of functional markers and a more realistic micro-anatomy. Additionally, these hypoxic-enhanced kidney organoids show a great potential as in vitro models for renal cystic diseases, as they efficiently generate cystic formations and display high sensitivity to drugs. This hypoxia approach may open new avenues for an enhanced understanding of kidney development and diseases.

Expansion of human iPSC-derived ureteric bud organoids with repeated branching potential [DiI-VLDL]

Project description:Ureteric bud (UB) is the embryonic kidney progenitor tissue that gives rise to the collecting duct and lower urinary tract. UB-like structures generated from human pluripotent stem cells by previously reported methods show limited developmental ability and limited branching. Here we report a new method to generate UB organoids that possess epithelial polarity and tubular lumen and repeat branching morphogenesis. We also succeeded in monitoring UB tip cells by utilizing the ability of tip cells to uptake very-low-density lipoprotein, cryopreserving UB progenitor cells and expanding UB tip cells that can reconstitute the organoids and differentiate into collecting duct progenitors. Moreover, we successfully reproduced some phenotypes of multicystic dysplastic kidney (MCDK) using the UB organoids. These methods will help elucidate the developmental mechanisms of UB branching and develop a selective differentiation method for collecting duct cells, contributing to the creation of disease models for congenital renal abnormalities.

A modular differentiation system maps multiple human kidney lineages from pluripotent stem cells [scRNA-Seq]

Project description:Recent studies using human pluripotent stem cells (hPSCs) have developed protocols to induce kidney-lineage cells and reconstruct kidney organoids. However, the separate generation of metanephric nephron progenitors (NPs), mesonephric NPs and ureteric bud (UB) cells, which constitute embryonic kidneys, in in vitro differentiation culture systems has not been fully investigated. Here we created a culture system in which these mesoderm-like cell types as well as paraxial and lateral plate mesoderm-like cells were separately generated from hPSCs. We succeeded in recapitulating nephrogenic niches from separately induced metanephric NP-like and UB-like cells, which were subsequently differentiated into glomeruli, renal tubules and collecting ducts in vitro and further vascularized in vivo. Our selective differentiation protocols should contribute to understanding the mechanisms underlying human kidney development and diseases and also supply cell sources for regenerative therapies.

Gene expression profile of zebrafish renal collecting ducts

Project description:The kidney is the main hematopoietic organ in teleost fish. Various stages of hematopoietic cells were observed in the interstitial tissue of the kidney. We recently demonstrated that zebrafish hematopoietic stem cells (HSCs) expressing jam1a were specifically localized along the renal collecting ducts in the adult kidney. Interestingly, most of HSCs invaded into the intracellular spaces of the epithelium in collecting ducts, suggesting that collecting ducts provide a specific microenvironment for HSCs. In order to identify niche factors in collecting ducts, we performed microarray analysis in collecting ducts isolated from the Tg(jam1a:EGFP) zebrafish kidney. Collecting ducts were isolated from Tg(jam1a:EGFP) zebrafish under a fluorescent microscope. To examine the effect of X-ray irradiation on the niche, collecting ducts were isolated from the fish irradiated with 25Gy. The whole kidney tissues were also used for a comparison analysis. Two independent replicates consisting of five zebrafish were prepared for each sample.

Project description:Here, establishing expansion cultures of hiPSC-derived ureteric bud tip cells, an embryonic precursor that gives rise to collecting ducts, we succeeded in advancing the developmental stage of collecting duct organoids and showed that all collecting duct organoids derived from PKD1-/- hiPSCs spontaneously develop multiple cysts, clarifying the initiation mechanisms of cystogenesis.

Identification of down-stream targets of Notch signaling within the developing mosue kidney collecting ducts.

Project description:Notch signaling deficient kidney collecting ducts may serve as a useful resource to identify principal cell lineage and intercalated lineage specific factors since they develop a reduced number of principal cells and an increased number of intercalated cells compared with wild type kidney collecting ducts. We compared RNA from three E18.5 mouse kidneys per group: HoxB7Cre;RBPJf/-;Rosa+/Eyfp (Notch signaling deficient; mutant) versus RBPJf/f;Rosa+/Eyfp (wild type).
