ASH2L controls ureteric bud morphogenesis via regulation of RET/GFRA1 signaling activity [CUT&Tag]

ABSTRACT: To elucidate the role of H3K4 methylation in metanephros development, we selectively inactivated ASH2L, core subunit of the COMPASS complex in mice UB lineage. We then performed histone H3K4me3 modification landscape profiling of the control (Hoxb7Cre-GFP+,Ash2l F/+) and mutant (Hoxb7Cre-GFP+,Ash2l F/F) FACS-sorted UB lineage cells at E16.5 by CUT&Tag-seq.

ASH2L controls ureteric bud morphogenesis via regulation of RET/GFRA1 signaling activity [RNA-seq]

Project description:To elucidate the role of H3K4 methylation in metanephros development, we selectively inactivated ASH2L, core subunit of the COMPASS complex in mice UB lineage. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different FACS-sorted UB lineage cells at E16.5 of the control and cKO mouse embryos.

Expression data from mouse embryonic ureteric bud (UB) cells

Project description:Dicer-dependent miRNAs are required for UB morphogenesis and differentiation during metanephric kidney development. We used microarray analysis to identify genes whose expression in the UB epithelium are altered from UB-specific ablation of Dicer.

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.

Expansion of human iPSC derived ureteric bud organoids with repeated branching potential

Project description: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.

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.
