Human iPSC derived posterior gut progenitors are expandable and capable of forming gut and liver organoids

ABSTRACT: Organoid technology provides a revolutionary paradigm towards therapy, yet to be applied in humans mainly because of the reproducibility and scalability challenges. Here, we overcome these limitations by evolving scalable organ bud production platform entirely from human induced pluripotent stem cells (iPSC). By conducting massive ‘reverse’ screen experiments, we identified effective triple progenitor populations for generating liver buds in a highly reproducible manner: hepatic endoderm, endothelial and septum mesenchyme progenitors. Furthermore, we achieved human scalability by developing an omni-well-array culture platform for mass-producing homogenous and miniaturized liver buds on a clinically relevant large scale (>108-cell scale). Vascularized and functional liver tissues generated entirely from iPSC significantly improved subsequent hepatic functionalization potentiated by stage-matched developmental progenitor interactions, enabling functional rescue against acute liver failure via transplantation. Overall, our study provides a stringent manufacture platform for multi-cellular organoid supply, thus facilitating clinical and pharmaceutical applications especially for the treatment of liver diseases through multi-industrial collaborations.

Hepatic differentiation of liver organoids

Project description:We analyzed gene expression profiles of self-organizing, multi-cellular, 3D liver organoids derived by co-culture of induced Pluripotent Stem Cell and stromal progenitors. We report the RNA-seq results of liver organoid at day0, day2, day4, day6 of co-culture. We also report RNA-seq results of constituent of the liver organoid, which are human iPSC at hepatic specification stage, human Mesenchymal stem cells derived from bone marrow, human umbilical vein endothelial cell. As controls, we also report RNS-seq results of un-differentiated human iPSC, human iPSC at definitive endoderm stage, human liver tissue, and primary cultured human hepatocytes isolated from unused donor livers.

Integrative analysis of transcriptomic and epigenomic dynamics of liver organoids using single cell RNA-seq and ATAC-seq.

Project description:In this study, to identify the heterogeneity and dynamics of transcriptome and epigenome of liver organoid in single cell level, we applied single cell RNA-seq (scRNA-seq) and single cell ATAC-seq (scATAC-seq) using Chromium’s 10x platform. We analyzed liver organoids treated with two medium conditions (hepatic medium - HM and differentiation medium - DM).

Bulk RNA-seq of MilliporeSigma 3DGro human patient-derived gastrointestinal organoid lines compared to SCC300 human iPSC-derived colon organoid line

Project description:Transcriptomic profiles of 6 commercially-available human patient-derived gastrointestinal organoid lines were obtained and compared to transcriptomic profile of a commercially available human iPSC-induced colon organoid line. Transcriptomic profile of iPSC-derived human colon organoid line was compared after culture in either Corning growth-factor-reduced Matrigel (Corning 356231) or MilliporeSigma growth-factor-reduced ECMGel (E6909)

Heterogeneous liver tissues with biliary branching and vascular elements through organoid bioprinting

Project description:Liver is dynamic, heterogeneous, and each cell type acts in concert to regulate its function. In vitro morphogenesis is limited, and self-assembled biliary and blood vessels system are absent from manufactured liver tissues. The combination of bioprinting and organoid technique offers spatial and cellular control over three-dimensional (3D) organ tissue manufacturing, allowing to build liver tissues with self-assembled structure in vitro. We developed a high-throughput PDMS microwell platform (PMP) generating uniform and functional hepatic organoid building blocks (HOBBs) which displayed cellular crosstalk and self-assembled structure. For bioprinting process, we developed three-level temperature control system and new quadratic material, i.e., alginate-gelatin-collagen-laminin (AGCL) biomaterial, realizing reproducible construction of liver tissues with requisite cellular density. Under long-term differentiation, bioprinted liver tissues exhibited enhanced hepatobiliary function, intrahepatic bile duct networks and angiogenic potential. To investigate the regulatory mechanisms of multicellular crosstalk and self-assembled of HOBBS, biliary branching morphogenesis, biomimetic liver tissue formation, and angiogenesis of HABs, transcriptome analysis was performed.

Highly reproducible and cost-effective one-pot organoid differentiation using a novel platform based on PF-127 triggered spheroid assembly

Project description:Using a novel platform based on the findings that Pluronic F-127 (PF-127) could trigger highly uniform spheroid assembly, we develop a one-pot organoid differentiation strategy. Using our strategy, we successfully generate cortical, nephron, hepatic, and lung organoids with improved reproducibility compared to previous methods while reducing the original costs by 80-95%. In addition, we adapt our platform to microfluidic chips allowing automated culture. We showcase that our platform can be applied to tissue-specific screening, such as drug toxicity and transfection reagents testing. And, we generate NEAT1 knockout tissue-specific organoids and show NEAT1 modulates multiple signaling pathways fine-tuning the differentiation of nephron and hepatic organoids and suppresses immune responses in cortical organoids. In summary, our strategy provides a powerful platform for advancing organoid research and studying human development and diseases.

Single-cell ATAC-seq of bonobo cerebral organoids

Project description:Single cell ATAC-seq (scATAC-seq) was performed on bonobo induced pluripotent stem cells (iPSC) derived cerebral organoids. scATAC-seq was performed on day 60 (2 months old cerebral organoid) and day 120 (4 months old cerebral organoid).

Longitudinal scRNA-seq analysis of human liver bud organoid (HLBO) with iPS-derived liver sinusoidal endothelial progenitor (iLSEP)

Project description:We directly differentiated human pluripotent stem cells into CD32b+ putative liver sinusoidal progenitors (iLSEP) by dictating developmental pathways. By devising an inverted multilayered air-liquid interface (IMALI) culture, hepatic endoderm, septum mesenchyme, arterial and sinusoidal quadruple progenitors self-organized to generate vascularized liver bud organoid. To uncover cellular characteristics and diversity during organoid development at transcriptomic level, time-series single cell RNA-seq (scRNA-seq) data were acquired.

Serotonin signals through a gut-liver axis to regulate hepatic steatosis

Project description:Purpose: While various functions of peripheral serotonin are known, the direct role of serotonin in regulating hepatic lipid metabolism in vivo is not well understood. We studied whether serotonin directly acts on liver to regulate lipid metabolism. Methods: Methods: 12 weeks aged liver-specific Htr2a KO (Albumin-Cre+/-; Htr2aflox/flox, herein named Htr2a LKO) mice and wildtype (WT) littermates were fed a high-fat diet (HFD, 60% fat calories) for 8 weeks. Results: Hepatic lipid droplet accumulation, NAFLD activity score, and hepatic triglyceride levels were dramatically reduced in HFD-fed Htr2a LKO mice compared to WT littermates. Conclusions: Gut-derived serotonin is a direct regulator of hepatic lipid metabolism via a gut TPH1-liver HTR2A endocrine axis. And shows promise as a novel drug target to ameliorate NAFLD with minimal systemic metabolic effects.
