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. E15.5 UB cells from control and Dicer mutant kidneys were FACS sorted for transcription profiling.

Mouse embryonic kidneys (E13.5): mutant (UB HDAC1,2-/-) vs. wild type

Project description:Transcriptional profiling of mouse embryonic kidneys (E13.5) comparing UB HDAC1,2-/- kidneys with wild type kidneys. Studies in our lab showed that histone deacetylase 1 (HDAC1) and 2 (HDAC2) perform redundant, yet essential functions in the developing mouse ureteric bud (UB) tissue. Double deletion of HDAC1 and HDAC2 in the UB results in impaired UB branching morphogenesis, followed by severe kidney dysgenesis. The goal of the microarray analysis was to identify the genetic pathways controlled by HDAC1 and 2 in the UB.

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.

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

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 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.

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.

Gene expression of p53 null vs. p53 wild-type mouse kidneys at embryonic day 15.5

Project description:Gene expression microarray analysis was performed on E15.5 p53+/+ and p53-/- litter-matched kidneys. We have previously shown that p53 is expressed in both UB and MM lineages in the kidney, and that p53-null embryos on C57B6L background exhibit a range of congenital abnormalities of the kidney and urinary tract such as duplicated ureters, reduced nephron numbers, and compromised nephron progenitor renewal and differentiation. Here our goal was to reveal the p53 transcriptome in mouse embryonic kidneys at E15.5.
