Retinoic acid signaling activation in early intermediate mesoderm differentiation promotes dual lineage of intermediate mesoderm specification and enhances full-segment kidney organoid generation

ABSTRACT: During kidney development, an intermediate mesoderm (IM) give rise to distinct structures: the ureteric bud (UB) and the metanephric mesenchyme (MM). These structures differentiate further into the collecting duct and nephron, forming a mature kidney. Generating functional kidney organoids has been challenging due to incomplete development of the UB. Researchers have overcome this limitation by differentiating UB and MM separately and co-culturing them to generate kidney organoids. However, this study developed a co-culture-free method using retinoic acid (RA), plays important role in the anterior IM differentiation and BMP7 secreted by UB in vivo development. This protocol provided not only simplifies the complexity of kidney organoid generation but also advances our understanding of the crucial signaling pathways involved in kidney development.

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

Project description: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.

Generation of nephronal cells from human pluripotent stem cells via renal-vesicle formation

Project description:Human pluripotent stem cells (hPSC) provide a possible source for generation of kidney cells and organoids applicable in regenerative medicine, disease modeling and drug screening. By analyzing the effect of different factors on renal differentiation, we established an 8-day-protocol that steered hPSCs to the renal lineage by a step-wise process, segmented into mesoderm induction, intermediate mesoderm specification and metanephric induction outlining renal organogenesis. The differentiated cells contain populations of SIX2+/CITED1+ metanephric mesenchyme- (MM) and of HOXB7+/GRHL2+ ureteric bud (UB)-like cells at the end of 6 days. Transcriptome analysis corroborated that the in vitro generated precursor cell types at day 8 resemble their renal vesicle counterparts in vivo. The cells were further differentiated in 2-dimensional culture into podocyte- and diverse tubular epithelial-like cell types, showing their nephrogenic potential. In 3-dimensional culture, the progenitors gave rise to renal vesicles, and upon mouse embryonic kidney re-aggregation they form tubular structures.

Hepatocyte nuclear factor 1β gene regulation in E14.5 ureteric bud cells

Project description:HNF-1β mutations are one of the most common single-gene mutations that underlie kidney developmental disease. Hepatocyte nuclear factor 1β (HNF-1β) is essential for kidney development, but its functions in ureteric bud (UB) branching morphogenesis are incompletely understood. We isolated E14.5 UB cells using fluorescence-activated cell sorting, and performed RNA-sequencing to compare gene expression in wild-type and HNF-1β deficient UB cells. 1632 genes have significantly lower expression in the HNF-1β deficient UB cells and 2223 genes have significantly higher expression in HNF-1β deficient UB cells.

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.
