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.

Project description:Proteinuria is pathogenic to proximal tubular cells (PTC) and linked with progression to renal failure. Angiotensin II (AngII) is also independently involved in the pathogenesis of progressive renal injury in varied kidney disease. The effects of human serum albumin (HSA) overload, AngII and candesartan, a specific inhibitor of AngII type 1 recptor, on the changes in gene protein expression stimulated by oxidative stress in PTC were assesed using cDNA microarrays. Keywords: stress response Cells were growth arrested for 48 h in serum-free DMEM/Ham's F-12 medium with 5.5 mM glucose, 2 mM L-glutamine,100 U/ml penicillin, 100 ug/ml streptomycin, 20 mM Hepes. Media were refreshed and cells were incubated for 24h in conditioned media alone, or with media supplemented with 30mg/ml of different HSA preparations, 1 uM AngII or AngII in the presence of candesartan. After further 24 h under standard cell culture conditions (37C, 5% CO2) cells were subjected to RNA extraction.

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.

Project description:The genetic background of mice used in this study is mainly C57BL/6J with a small contribution from 129/Sv and DBA/2J strains. Male littermates were received continuous administration of AngII for 7 days at 0.9ug/hour. On day 7 of AngII infusion, the blood pressure of infused mice was (mmHg, mean ± SD) 156 ± 1, while the control littermates remained normotensive (106 ± 9). Keywords: other

Project description:We have employed whole genome microarray expression profiling as a platform to identify AngII -regulated genes sensitive to CsA. VSMC were treated with AngII with or without CsA ( as an inhibitor of the CN/NFAT pathway). 4 independent VSMC cultures (4 replicates) from aortas of C57BL/6 mice were used for each condition (1uM AngII or 1uM AngII+200ng/ml CsA).

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. Two-condition experiment: E13.5 mutant kidneys (UB HDAC1,2-/-) vs. E13.5 wild type kidneys . Biological replicates: 4 control replicates, 4 UB HDAC1,2-/- replicates. Two-color Agilent 4x44k chips with dye-swaps on 2 of 4 arrays.
