Transplanted human organoids empower PK/PD assessment of drug candidate for the clinic

ABSTRACT: Pharmacokinetic/pharmacodynamic (PK/PD) studies are an essential component of pre-clinical drug discovery. Current best approaches for PK/PD studies, including the analysis of novel kidney disease targeting therapeutic agents, are limited to animal models with unclear translatability to the human condition. To address this challenge, we developed a novel approach for PK/PD studies using transplanted human kidney organoids. We performed PK studies with GFB-887, an investigational new drug now in Phase 2 trials. Orally dosed GFB-887 to athymic rats that had undergone organoid transplantation resulted in measurable drug exposure in human transplanted organoids. Importantly, we established the efficacy of orally dosed GFB-887 in PD studies, where quantitative analysis showed significant protection of kidney filter cells in human organoids and endogenous rat host kidneys. This widely applicable approach demonstrates, for the first time, feasibility of using transplanted human organoids in PK/PD studies, empowering organoids to revolutionize drug discovery.

scRNAseq of human iPSC-derived kidney organoids transplanted in the coelomic cavity of chicken embryos compared to untransplanted controls

Project description:Human induced pluripotent stem cell-derived kidney organoids have potential for disease modelling and regenerative medicine purposes. However, they lack a functional vasculature and remain immature in in vitro culture. Here, we transplanted kidney organoids at day 7+12 of differentiation in the coelomic cavity of chicken embryos and then compared them to their respective untransplanted controls at d7+13 and d7+20 using scRNAseq and imaging modalities. We demonstrate vascularization and enhanced maturation of transplanted kidney organoids.

Generating Patterned Kidney Organoids for Studying Development and Diseases [bulk RNA-Seq]

Project description:Human pluripotent stem cells (hPSCs)-derived kidney organoids recapitulate complex developmental processes and tissue architectures, but the intrinsic limitations, such as variability and a lack of vasculature, have greatly hampered their application. Here we establish a highly efficient and versatile protocol for generating vascularized three-dimensional (3D) kidney organoids. We employ dynamic modulation of WNT signaling to control the relative proportion of proximal versus distal nephron segments, thereby producing a correlative level of VEGFA to define the resident vascular network. By single cell RNA-sequencing, we identify a subset of nephron progenitor cells as a potential source of the vasculature. Upon implantation into host mice, these kidney organoids undergo further structural and functional maturation, as demonstrated by the size-selective handling of dextran. Based on this differentiation platform, we establish an in vitro model of autosomal recessive polycystic kidney disease (ARPKD) by differentiating induced PSCs (iPSCs) from an ARPKD patient into 3D kidney organoids that develop tubule cysts in response to cAMP upregulation. The cystogenesis phenotype can be effectively prevented by gene correction or drug treatment. Our studies provide a versatile platform for studying human kidney development and diseases, and opens new avenues for modeling disease pathogenesis and performing patient-specific drug screening.

Developing a novel human adult kidney organoid model to recapitulate injury-associated regeneration and polycystic kidney disease [scRNA-Seq]

Project description:Current renal organoid models derived from embryonic or induced pluripotent stem cells mimic development. Yet, few studies have attempted to generate organoids from human adult kidney to recapitulate regeneration or pathological dysregulation in vitro. Here, we report a novel expanding regenerative organoids culture system from renal cortex and medulla. Transcriptomic sequencing and immunostaining identified that these organoids share similar molecular features with kidney injury-responsive regeneration. Heterogeneous populations in organoids including cycling epithelial progenitors and differentiated cell types were identified by single cell sequencing including proximal tubules, principal cells and collecting duct (CD) progenitors that can be induced into functional CD system. Furthermore, we established polycystic organoids derived from patients that represent an advanced platform for polycystic kidney disease (PKD) modeling. By drug screening, QNZ, GSK2193874 and AMPK activators were shown to significantly reduce polycystic growth. Our results demonstrated a novel in vitro renal organoid model to study regenerating adult renal cells and PKD mechanism, providing tools for discovery of therapeutic targets.

iPSC-derived type IV collagen α5-expressing kidney organoids model Alport syndrome

Project description:Alport syndrome (AS) is a hereditary glomerulonephritis caused by COL4A3, COL4A4 or COL4A5 gene mutations and characterized by abnormalities of glomerular basement membranes (GBMs). Due to a lack of curative treatments, the condition proceeds to end-stage renal disease even in adolescents. Hampering drug discovery is the absence of effective in vitro methods for testing the restoration of normal GBMs. Here, we aimed to develop kidney organoid models from AS patient iPSCs for this purpose. We established iPSC-derived collagen α5(IV)-expressing kidney organoids and confirmed that kidney organoids from COL4A5 mutation-corrected iPSCs restore collagen α5(IV) protein expression. Importantly, our model recapitulates the differences in collagen composition between iPSC-derived kidney organoids from mild and severe AS cases. Furthermore, we demonstrate that a chemical chaperone, 4-phenyl butyric acid, has the potential to correct GBM abnormalities in kidney organoids showing mild AS phenotypes. This iPSC-derived kidney organoid model will contribute to drug discovery for AS.

The immunogenicity of human kidney organoids

Project description:Safety issues of human iPSC-derived kidney organoids as a regenerative therapy need to be evaluated. Therefore, we studied the immunogenicity of human iPSC-derived kidney organoids. We subcutaneously implanted kidney organoids in immune-deficient IL2Ry-/-RAG2-/- mice for 1 month and hereafter performed adoptive transfer of healthy allogeneic human PBMC. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of kidney organoid cells and immune cell profiles. We investigated whether innate and adaptive immune cells invade kidney organoids, evoke an immune response, and influence the kidney organoid differentiation and functional capacity. Understanding the immunogenicity of kidney organoids will advance studies in the applicability of kidney organoids for regenerative medicine. Furthermore, it can serve as an in-vivo transplantation model to study solid organ transplantation.
