Human-induced pluripotent Stem Cell-Derived Hepatic Stellate Cells in Liver Organoids: Maturation Promotion and Essential Role in Vascularization [scRNA-Seq]

ABSTRACT: Human-induced pluripotent stem cell (hiPSC)-derived liver organoids (LOs) are valuable for studying human liver organogenesis but face challenges in faithfully recapitulating certain processes, like vasculogenesis, due to the lack of specific cell components. Hepatic stellate cells (HSCs), which are liver-specific pericytes and might be crucial for liver vasculogenesis, remain underutilized in developmental studies because of their disease-related "activated" status and inefficient generation process. Here, we present an efficient method for generating hiPSC-derived HSCs (hiPSC-HSCs) resembling fetal HSCs’ transcriptomic profiles. These hiPSC-HSCs exhibit exceptional expandability (>105-fold) while maintaining essential cellular features. Additionally, in entirely hiPSC-derived LOs consisting of HSCs, hepatic endoderm, and endothelial cells, hiPSC-HSCs play a vital role in LO maturation and vascularization, both in vitro and in vivo. This work represents a significant advancement in understanding HSC roles in human liver development, and LOs containing non-activated hiPSC-HSCs hold potential in modeling congenital human liver diseases.

Human iPSC-liver organoid transplant reduces fibrosis by immunomodulation

Project description:Donor organ shortage for transplant is a serious problem worldwide. Organoid culture technology, which allows the generation of complex organs from stem cells, provides a potential solution. We previously reported in vivo vascularization of human induced pluripotent stem cell (hiPSC)-derived liver buds (LBs) and subsequent improved survival of recipient mice with acute liver failure1,2. Here, we show that mid-gestational fetal liver tissue can generate de novo liver when grafted onto the surface of host livers and improve survival and liver functions in a model of liver failure. Next, we created complex fetal liver-like organoids (LOs) by a fusion of hiPSC-LBs to induce static cell-cell interactions, and show that these contain hepatocytes, vasculature, and bile duct after transplantation. Fused hiPSC-LOs show superior liver functions compared to hiPSC-LBs and improve survival and functions of liver failure model upon transplantation. Finally, transplant of fused hiPSC-LOs ameliorates liver fibrosis, a symptom of liver cirrhosis which leads to organ dysfunction, through their immunomodulatory effects especially on macrophage polarization that plays an important role in the regulation of liver fibrosis3–5. Taken together, our results suggest that hiPSC-LO transplant could be a promising therapeutic option for liver failure patients in the near future

Single-Cell Analysis of Heterogeneity in Reverted Human iPSC-Derived Hepatic Stellate Cells

Project description:We employed a single-cell RNA sequencing (scRNA-seq) approach using the 10x Genomics platform to investigate the heterogeneity of reverted hepatic stellate cells (HSCs) derived from human induced pluripotent stem cells (hiPSCs). HSCs are key mediators of liver fibrosis; although their activation is well known to drive fibrogenesis, their fate following removal of the fibrogenic insult remains poorly understood. To address this, we utilized a hiPSC-derived liver culture system comprising hepatocytes, HSCs, and macrophages. HSCs were activated by hepatitis C virus (HCV) infection and subsequently treated with antivirals to achieve viral clearance. Reverted HSCs were then characterized through gene expression profiling, vitamin A quantification, functional assays, and scRNA-seq. Our data reveal that activated HSCs exhibit plasticity and can revert to a quiescent-like state upon removal of the activating stimulus, although they retain heightened sensitivity to re-stimulation. These findings enhance our understanding of HSC dynamics and highlight potential therapeutic strategies targeting HSC reversion to treat liver fibrosis.

Development of human iPSC-derived quiescent hepatic stellate cell-like cells for drug discovery and in vitro disease modeling

Project description:Hepatic stellate cells (HSCs) play a central role in the progression of liver fibrosis by producing extracellular matrices. The development of drugs to suppress liver fibrosis has been hampered by the lack of human quiescent HSCs (qHSCs) and an appropriate in vitro model that faithfully recapitulates HSC activation. In the present study, we developed a culture system to generate qHSC-like cells from human-induced pluripotent stem cells (hiPSCs) that can be converted into activated HSCs in culture. To monitor the activation process, a red fluorescent protein (RFP) gene was inserted in hiPSCs downstream of the activation marker gene actin alpha 2 smooth muscle (ACTA2). Using qHSC-like cells derived from RFP-reporter iPSCs, we screened a repurposing chemical library and identified therapeutic candidates that prevent liver fibrosis. Hence, hiPSC-derived qHSC-like cells will be a useful tool to study the mechanism of HSC activation and to identify therapeutic agents.

Vascularised and functional human liver from an iPSC-derived organ bud transplant

Project description:Critical shortage of donor organs for treating end-stage organ failure highlights the urgent need for generating organs from induced pluripotent stem cells (hiPSCs). Despite many reports describing functional cell differentiation, no studies have succeeded in generating a three-dimensional vascularised organ such as liver. Here, we show the generation of vascularised and functional human liver from hiPSCs by transplantation of liver buds created in vitro (hiPSC-LBs). Specified hepatic cells self-organised into three-dimensional hiPSC-LBs by recapitulating organogenetic interactions between endothelial and mesenchymal cells. Immunostaining and gene expression analyses revealed resemblance between in vitro grown hiPSC-LBs and in vivo liver buds. Human vasculatures in hiPSC-LB transplants became functional by connecting to the host vessels within 48 hours. The formation of functional vasculatures stimulated the maturation of hiPSC-LBs into tissue resembling the adult liver. Highly metabolic hiPSC-derived tissue performed liver-specific functions such as protein production and human-specific drug metabolism without recipient liver replacement. Comparison of liver developmental gene signatures among hiPSC-LB, hFLC-LB, human adult (30 years old) liver tissues (hALT) and mouse liver tissue (mLT) of various developmental stages (E9.5~P8weeks).

microRNA profiles of hematopoietic derivatives

Project description:Hematopoietic stem cells (HSCs) can regenerate the entire hematopoietic system in vivo, providing the most relevant criteria to measure candidate HSCs derived from human embryonic stem cell (hESC) or induced pluripotent stem cell (hiPSC) sources. Here, we show that unlike primitive hematopoietic cells derived from hESCs, phenotypically identical cells derived from hiPSC are more permissive to graft the bone marrow of xenotransplantation recipients. Despite establishment of bone marrow graft, hiPSC-derived cells fail to demonstrate hematopoietic differentiation in vivo. However, once removed from recipient bone marrow, hiPSC-derived grafts were capable of in vitro multilineage hematopoietic differentiation, indicating that xenograft imparts a restriction to in vivo hematopoietic progression. This failure to regenerate multilineage hematopoiesis in vivo was attributed to the inability to downregulate key microRNAs involved in hematopoiesis. Based on these analyses, our study indicates that hiPSCs provide a beneficial source of pluripotent stem cell-derived hematopoietic cells for transplantation compared with hESCs. Since use of the human-mouse xenograft models prevents detection of putative hiPSC-derived HSCs, we suggest that new preclinical models should be explored to fully evaluate cells generated from hiPSC sources. Human pluripotent stem cell-derived hematopoietic cells were isolated and qPCR-based microRNA profiling was performed.

Glycolysis in hepatic stellate cells coordinates fibrogenic extracellular vesicle release spatially to amplify liver fibrosis

Project description:Liver fibrosis is characterized by the activation of perivascular hepatic stellate cells (HSCs), the release of fibrogenic nano-sized extracellular vesicles (EVs) and increased HSC glycolysis. Nevertheless, how glycolysis in HSCs coordinates fibrosis amplification through tissue zone-specific pathways remains elusive. Here, we demonstrate that HSC-specific genetic inhibition of glycolysis reduced liver fibrosis. Moreover, spatial transcriptomics revealed a fibrosis-mediated upregulation of EV-related pathways in the liver pericentral zone, which was abrogated by the glycolysis genetic inhibition. Mechanistically, glycolysis in HSCs upregulated the expression of EV-related genes such as RAB31 by enhancing histone-3-lysine-9 acetylation on the promoter region, which increased EV release. Functionally, these glycolysis-dependent EVs increased fibrotic gene expression in recipient HSC. Furthermore, EVs derived from glycolysis-deficient mice abrogated liver fibrosis amplification in contrast to glycolysis-competent mouse EVs. In summary, glycolysis in HSCs amplifies liver fibrosis by promoting fibrogenic EV release in the hepatic pericentral zone, which represents a potential therapeutic target.
