Generation of nephronal cells from human pluripotent stem cells via renal-vesicle formation

ABSTRACT: Human pluripotent stem cells (hPSC) provide a possible source for generation of kidney cells and organoids applicable in regenerative medicine, disease modeling and drug screening. By analyzing the effect of different factors on renal differentiation, we established an 8-day-protocol that steered hPSCs to the renal lineage by a step-wise process, segmented into mesoderm induction, intermediate mesoderm specification and metanephric induction outlining renal organogenesis. The differentiated cells contain populations of SIX2+/CITED1+ metanephric mesenchyme- (MM) and of HOXB7+/GRHL2+ ureteric bud (UB)-like cells at the end of 6 days. Transcriptome analysis corroborated that the in vitro generated precursor cell types at day 8 resemble their renal vesicle counterparts in vivo. The cells were further differentiated in 2-dimensional culture into podocyte- and diverse tubular epithelial-like cell types, showing their nephrogenic potential. In 3-dimensional culture, the progenitors gave rise to renal vesicles, and upon mouse embryonic kidney re-aggregation they form tubular structures.

A modular differentiation system maps multiple human kidney lineages from pluripotent stem cells [scRNA-Seq]

Project description:Recent studies using human pluripotent stem cells (hPSCs) have developed protocols to induce kidney-lineage cells and reconstruct kidney organoids. However, the separate generation of metanephric nephron progenitors (NPs), mesonephric NPs and ureteric bud (UB) cells, which constitute embryonic kidneys, in in vitro differentiation culture systems has not been fully investigated. Here we created a culture system in which these mesoderm-like cell types as well as paraxial and lateral plate mesoderm-like cells were separately generated from hPSCs. We succeeded in recapitulating nephrogenic niches from separately induced metanephric NP-like and UB-like cells, which were subsequently differentiated into glomeruli, renal tubules and collecting ducts in vitro and further vascularized in vivo. Our selective differentiation protocols should contribute to understanding the mechanisms underlying human kidney development and diseases and also supply cell sources for regenerative therapies.

mRNA sequencing of wildtype versus CEP83 knockout hiPSCs at diffirent time points of differentiation to kidney organoids [scRNA-seq]

Project description:Centrosomal protein 83 (CEP83) is a component of the distal appendages proteins of centrioles, which is necessary for the assembly of primary cilia. Previous studies have implicated primary cilia in normal development and tissue homeostasis, including kidney development. The kidney develops from human induced pluripotent stem cell (hiPSCs) in a stepwise process involving induction of specialized Nephron progenitors (NPs) in the intermediate mesoderm (IM), followed by their differentiation into kidney epithelia. Here, we used CRISPR-cas9 technology to knockout CEP83 in hiPSCs that were differentiated versus the wildtype hiPSCs into IM followed by kidney epithelial differentiation to analyze the role of CEP83 in human kidney epithelial differentiation. We used morphological analyses, gene expression studies and immunostaining to analyze IM and nephron differentiation. Bulk RNA and single cell sequencing showed that CEP83-/- IM cells abnormally upregulate regulatory transcription factors of lateral plate mesoderm (LPM) including OSR1, FOXF1, FOXF2, HAND2 and FEDRR., and downregulate marker genes in specific NPs ncluding; PAX8, HOXB7 and EYA1. Further, wildtype hiPSCs successfully differentiated into kidney organoids that upregulate key nephron markers, including NPHS1, CUBN and GATA3. In contrast, CEP83-/- hiPSCs failed to differentiate into nephron epithelia and didn’t express nephron marker genes. In a human system modeling kidney epithelial differentiation from hiPSCs, our data provide a new insight to the essential role of CEP83 in NPs differentiation and may help to better understand the pathogenesis of CEP83-associated renal developmental defects.

Cloning and variation of adult renal tubular progenitors

Project description:Kidney damage involves the progressive and inexorable destruction of tubular and glomerular system. However, it is known that the patients survive AKI often recover renal structure and function. Correspondingly, previous studies demonstrated tubular regeneration in mice after massive kidney injury and linked mouse Sox9+ renal progenitor cells to this process. Here we show that renal progenitor cells can be cloned from renal needle biopsy sample of CKD patients. Progenitor cells can readily assembly into “kidney organoids” expressing proximal/distal tubular cell markers in 3D culture.

Cloning and transplantation of adult renal tubular progenitors

Project description:Kidney damage involves the progressive and inexorable destruction of tubular and glomerular system. However, it is known that the patients survive AKI often recover renal structure and function. Correspondingly, previous studies demonstrated tubular regeneration in mice after massive kidney injury and linked mouse Sox9+ renal progenitor cells to this process. Here we show that progenitor cells can be cloned from mouse medulla and cortex. Clones can be grown from a single cell and indefinitely passaged. Progenitor cells derived from renal medulla can readily assembly into “kidney organoids” expressing proximal/distal tubular cell markers in 3D culture.

mTORC1 maintains renal tubular homeostasis and is essential in response to ischemic stress

Project description:The mechanistic target of rapamycin mTORC1 is a key regulator of cell metabolism and autophagy. Despite widespread clinical use of mTOR inhibitors, the role of mTORC1 in renal tubular function and kidney homeostasis remains elusive. By utilizing constitutive and inducible deletion of conditional Raptor alleles in renal tubular epithelial cells, we discovered that mTORC1 deficiency caused a marked concentrating defect, loss of tubular cells and slowly progressive renal fibrosis. Transcriptional profiling revealed that mTORC1 maintains renal tubular homeostasis by controlling mitochondrial metabolism and biogenesis as well as transcellular transport processes involved in counter-current multiplication and urine concentration. Although mTORC2 partially compensated the loss of mTORC1, exposure to ischemia and reperfusion injury exaggerated the tubular damage in mTORC1-deficient mice, and caused pronounced apoptosis, diminished proliferation rates and delayed recovery. These findings identify mTORC1 as an essential regulator of tubular energy metabolism and as a crucial component of ischemic stress responses. Pharmacological inhibition of mTORC1 likely affects tubular homeostasis, and may be particularly deleterious if the kidney is exposed to acute injury. Furthermore, the combined inhibition of mTORC1 and mTORC2 may increase the susceptibility to renal damage. Raptor fl/fl*KspCre and Raptor fl/fl animals were sacrificed at P14 before the development of an overt functional phenotype. Kidneys were split in half and immediately snap frozen in liquid nitrogen.

β-catenin-controlled tubular cell-derived exosomes play a key role in fibroblast activation via the OPN-CD44 axis

Project description:Tubular injury and peripheral fibroblast activation are the hallmarks of chronic kidney disease (CKD) and renal fibrosis, suggesting intimate communication between the two diseases. However, the underlying mechanisms remain to be determined. Exosomes play a role in shuttling proteins and other materials to recipient cells. In our study, we found that tubular cell-derived exosomes were aroused by β-catenin in kidney fibrogenesis. Osteopontin (OPN), especially its N-terminal fragments (N-OPN), was encapsulated in β-catenin-controlled tubular cell-derived exosome cargo, and subsequently passed to fibroblasts. Through binding with CD44, exosomal OPN promoted fibroblast proliferation and activation. Gene deletion of β-catenin in tubular cells (Ksp-β-catenin−/−) or gene ablation of CD44 (CD44−/−) greatly ameliorated renal fibrosis. Notably, N-OPN was secreted by exosome into the urine of patients with CKD, and negatively correlated with kidney function. The urinary exosomes from patients with CKD greatly accelerated renal fibrosis, which was blocked by CD44 deletion. These results suggest that exosome-mediated activation of the OPN/CD44 axis plays a key role in renal fibrosis, which is controlled by β-catenin.
