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

ABSTRACT: 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).

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.

Comprehensive single cell RNAseq analysis of the kidney reveals novel cell types and unexpected cell plasticity

Project description:We characterized 57,979 cells from healthy mouse kidneys using unbiased single-cell RNA sequencing. We show that genetic mutations that present with similar phenotypes mostly affect genes that are expressed in a single unique differentiated cell type. On the other hand, we found unexpected cell plasticity of epithelial cells in the final segment of the kidney (collecting duct) that is responsible for final composition of the urine. Using computational cell trajectory analysis and in vivo linage tracing, we found that, intercalated cells (that secrete protons) and principal cells (that maintain salt, water and potassium balance) undergo a Notch mediated interconversion via a newly identified transitional cell type. In disease states this transition is shifted towards the principal cell fate. Loss of intercalated cells likely contributes to metabolic acidosis observed in kidney disease.

Human Pluripotent Stem Cell-Derived Kidney Organoids for Modeling Epithelial Transport and Injury

Project description:Maximizing the potential of human kidney organoids for drug testing, regenerative medicine and to model development and disease requires addressing cell immaturity, the lack of a branching collecting system and the off target cell types. Here we establish methods to independently generate the two kidney progenitor cell populations – metanephric mesenchyme and ureteric bud. Combining these two progenitor cell types results in organoids with an improved branched collecting system. We also identified the hormones aldosterone and arginine vasopressin as critical to promote maturation of collecting duct cell types. The resulting organoids contain the full range of epithelial cells in the nephron, including principal and intercalated cells. By scRNA-seq, we demonstrate superior proximal tubule maturation and reduced off-target cell populations using this protocol.

Circadian gene profiling in the distal nephron and collecting ducts

Project description:Renal excretion of water and major electrolytes exhibits a significant circadian rhythm. This functional periodicity is believed to result, at least in part, from circadian changes in secretion/reabsorption capacities of the distal nephron and collecting ducts. Here, we studied the molecular mechanisms underlying circadian rhythms in the distal nephron segments, i.e. distal convoluted tubule (DCT) and connecting tubule (CNT) and, the cortical collecting duct (CCD). Temporal expression analysis performed on microdissected mouse DCT/CNT or CCD revealed a marked circadian rhythmicity in the expression of a large number of genes crucially involved in various homeostatic functions of the kidney. This analysis also revealed that both DCT/CNT and CCD possess an intrinsic circadian timing system characterized by robust oscillations in the expression of circadian core clock genes (clock, bma11, npas2, per, cry, nr1d1) and clock-controlled Par bZip transcriptional factors dbp, hlf and tef. The clock knockout mice or mice devoid of dbp/hlf/tef (triple knockout) exhibit significant changes in renal expression of several key regulators of water or sodium balance (vasopressin V2 receptor, aquaporin-2, aquaporin-4, alphaENaC). Functionally, the loss of clock leads to a complex phenotype characterized by partial diabetes insipidus, dysregulation of sodium excretion rhythms and a significant decrease in blood pressure. Collectively, this study uncovers a major role of molecular clock in renal function. Keywords: time course
