Molecular determinants of nephron vascular specialization in the kidney

Project description:The kidney vasculature is specialized to filter waste products from the blood, regulate blood pressure, and balance electrolytes. Although recent advances in stem cell studies have enabled the partial generation of kidney tissues in vitro, recapitulating the complex vascular structures of the kidney remains a daunting task. The molecular pathways that specify and sustain kidney vascular heterogeneity to perform these diverse tasks are not well characterized. Here, we have employed high throughput bulk and single-cell RNA sequencing of the non-lymphatic vasculature of the kidney to uncover the progression of pathways that dictate the developmental transition of nephrogenesis and vascular zonation from embryos to adulthood. We show that glomeruli and its associated vessels, manifest vascular-specific signatures expressing defined transcription factors, ion channels, solute transporters, and paracrine factors choreographing kidney functions. Notably, the ontology of the glomerulus coincides with induction of several unique transcription factors, including Tbx3, Gata5, Prdm1, and Pbx1. Selective deletion of Tbx3 in endothelial cells result in glomerular hypoplasia, microaneurysms and regressed fenestrations leading to fibrosis. Unraveling the molecular determinants of kidney vascular signatures will lay the foundation for rebuilding nephrons and understanding the pathogenesis of kidney diseases.

Molecular determinants of nephron vascular specialization in the kidney.

Project description:Although kidney parenchymal tissue can be generated in vitro, reconstructing the complex vasculature of the kidney remains a daunting task. The molecular pathways that specify and sustain functional, phenotypic and structural heterogeneity of the kidney vasculature are unknown. Here, we employ high-throughput bulk and single-cell RNA sequencing of the non-lymphatic endothelial cells (ECs) of the kidney to identify the molecular pathways that dictate vascular zonation from embryos to adulthood. We show that the kidney manifests vascular-specific signatures expressing defined transcription factors, ion channels, solute transporters, and angiocrine factors choreographing kidney functions. Notably, the ontology of the glomerulus coincides with induction of unique transcription factors, including Tbx3, Gata5, Prdm1, and Pbx1. Deletion of Tbx3 in ECs results in glomerular hypoplasia, microaneurysms and regressed fenestrations leading to fibrosis in subsets of glomeruli. Deciphering the molecular determinants of kidney vascular signatures lays the foundation for rebuilding nephrons and uncovering the pathogenesis of kidney disorders.

Modeling kidney development, disease, and plasticity with clonal expandable nephron progenitor cells and nephron organoids

Project description:Nephron progenitor cells (NPCs) self-renew and differentiate into nephrons, the functional units of the kidney. Here we report manipulation of p38 and YAP activity creates a synthetic niche that allows the long-term clonal expansion of primary mouse and human NPCs, and induced NPCs (iNPCs) from human pluripotent stem cells. Cultured iNPCs resemble closely primary human NPCs, generating nephron organoids with abundant distal convoluted tubule cells, which are not observed in published kidney organoids. The synthetic niche reprograms differentiated nephron cells into NPC state, recapitulating the plasticity of developing nephron in vivo. Scalability and ease of genome-editing in the cultured NPCs allow for genome-wide CRISPR screening, identi-fying novel genes associated with kidney development and disease. A rapid, efficient, and scala-ble organoid model for polycystic kidney disease was derived directly from genome-edited NPCs, and validated in drug screen. These technological platforms have broad applications to kidney development, disease, plasticity, and regeneration.

Repression of interstitial cell identity in nephron progenitor cells by Pax2 establishes the nephron-interstitium lineage boundary throughout mammalian kidney development

Project description:The kidney contains the functional units, the nephrons, surrounded by the renal interstitium. Previously, we discovered that, once Six2-expressing nephron progenitor cells and Foxd1-expressing renal interstitial progenitor cells form at the onset of kidney development, descendant cells from these populations contribute exclusively to the main body of nephrons and renal interstitial tissues, respectively, indicating a lineage boundary between the nephron and renal interstitial compartments. Currently, it is unclear how lineages are regulated during kidney organogenesis. We demonstrate that nephron progenitor cells lacking Pax2 activity failed to differentiate into nephron cells, but can switch fates into renal interstitium cell types. These data suggest that Pax2 function maintains nephron progenitor cells by repressing transdifferentiation into renal interstitial cell states. Thus, the lineage boundary between the nephron and renal interstitial compartments is maintained by the Pax2 activity in nephron progenitor cells during kidney organogenesis.
