Transcriptome characterization of organoids derived from healthy and irreversibly damaged NASH patient liver

ABSTRACT: Background and Aims: Nonalcoholic steatohepatitis (NASH) will soon become the leading cause of liver transplantation in the US and is also associated with increased COVID-19 mortality. Currently, there are no FDA approved drugs available that slow NASH progression or address NASH liver involvement in COVID-19. Since animal models cannot fully recapitulate human NASH, we hypothesized that stem cells isolated directly from end-stage NASH patient liver may address current knowledge gaps in human NASH pathology. Approach and Results: We devised methods allowing derivation, proliferation, hepatic differentiation and extensive characterization of bipotent ductal organoids from irreversibly damaged NASH patient liver. The transcriptomes of organoids derived from NASH liver, but not healthy liver show significant upregulation of pro-inflammatory and cytochrome p450-related pathways, as well as of known liver fibrosis and tumor markers, with the degree of upregulation being NASH patient-specific.

A Platform to Define Cellular Targets of SARS-COV-2 Infection Using Human Pluripotent Stem Cell-Derived Cells and Organoids

Project description:The SARS-CoV-2 virus has already caused over a million COVID-19 cases and over fifty-thousand deaths globally. There is an urgent need to create novel models to study SARS-CoV-2 virus using human disease-relevant cells and tissues to understand key features of virus biology. We present a platform comprised of nine different cell and organoid derivatives from human pluripotent stem cells (hPSCs) representing all three primary germ layers, including lung progenitors and alveolar type II (AT2) cells, pancreatic endocrine cells, liver organoids, endothelial cells, cardiomyocytes, macrophages, microglia, and both cortical and dopaminergic neurons. We systematically probed which cell types are permissive to SARS-CoV-2 infection. Human pancreatic beta cells and hepatocytes were strikingly permissive to SARS-CoV-2 infection, further validated using adult primary human islets and liver organoids. Both in vitro and in a humanized mouse model, human lung progenitors and AT2 cells express the ACE2 viral receptor and were highly permissive to SARS-CoV-2 infection. Transcriptomic analysis following SARS-CoV-2 infection of hPSC-derived pancreatic and lung organoids revealed upregulation of chemokines but not type I/III interferon signaling, similar to what was seen in primary human COVID-19 pulmonary infection. Therefore, hPSC-derived cells phenocopy human COVID-19 disease and provide a valuable resource to understand SARS-CoV-2 biology and search for novel therapeutics.

SARS-CoV-2 infects the human kidney and drives fibrosis in kidney organoids

Project description:Single-cell RNA-seq of iPSC derived human kidney organoids. Single-nuclei RNA-seq data of COVID-19 patient autopsy kidney tissue. The current data was used to suggest that SARS-CoV-2 can directly infect kidney cells and induce cell injury as well as a pro-fibrotic environment which could explain acute kidney injury in COVID-19 patients and also long-term effects potentially leading to the development of chronic kidney disease.

R-spondin 1 and noggin facilitate expansion of resident stem cells from non-damaged gallbladders.

Project description:Pioneering studies within the last few years have allowed the in vitro expansion of tissue-specific adult stem cells from a variety of endoderm-derived organs, including the stomach, small intestine and colon. Here we derived organoids from mouse gallbladder tissue (gallbladder organoids), from mouse liver (including the extrahepatic biliary ducts and gallbladder; liver organoids) and from mouse small intestine tissue (intestinal organoids). RNA was prepared from these organoids and used to assay expression of 21,258 genes using Affymetrix gene expression arrays. RNA was also prepared from mouse gallbladder, liver and small intestine tissues and used to assay gene expression in these tissues. Finally, gallbladder organoids were induced to differentiate by removing R-spondin 1 and noggin from the culture media and subjected to gene expression array analysis. RNA was extracted from mouse gallbladder organoids, differentiated gallbladder organoids, liver organoids, small intestine organoids, gallbladder tissue, liver tissue and small intestine tissue and then used for hybridization of Affymetrix gene expression microarrays.

Adult Stem Cell-derived Complete Lung Organoid Models Emulate Lung Disease in COVID-19

Project description:SARS-CoV-2, the virus responsible for COVID-19, causes widespread damage in the lungs in the setting of an overzealous immune response whose origin remains unclear. We present a scalable, propagable, personalized, cost-effective adult stem cell-derived human lung organoid model that is complete with both proximal and distal airway epithelia. Monolayers derived from adult lung organoids (ALOs), primary airway cells, or hiPSC-derived alveolar type-II (AT2) pneumocytes were infected with SARS-CoV-2 to create in vitro lung models of COVID-19. Infected ALO-monolayers best recapitulated the transcriptomic signatures in diverse cohorts of COVID-19 patient-derived respiratory samples. The airway (proximal) cells were critical for sustained viral infection, whereas distal alveolar differentiation (AT2→AT1) was critical for mounting the overzealous host immune response in fatal disease; ALO monolayers with well-mixed proximodistal airway components recapitulated both. Findings validate a human lung model of COVID-19 , which can be immediately utilized to investigate COVID-19 pathogenesis and vet new therapies and vaccines.

Binding of the spike of SARS-CoV-2 to steatotic hepatocytes promotes metabolic dysfunction

Project description:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes a multi-organ damage that includes hepatic dysfunction, which has been observed in over 50% of COVID-19 patients. Liver injury in COVID-19 patients could be attributed to the cytopathic effects induced by the interation between the virus and hepatic cells, exacerbated immune responses or treatment-associated drug toxicity. Here we demonstrate that primary hepatocytes are susceptible to infection in different models: hepatocytes derived from humanized angiotensin-converting enzyme-2 (hACE-2) mice and THLE-2 human cells. Pseudotyped viral particles engineered to express the full-length spike of SARS-CoV-2 and recombinant RBD bind to ACE2 expressed by hepatocytes, promoting metabolic reprogramming towards glycolysis but also mitochondrial dysfunction. In the context of non-alcoholic steatohepatitis (NASH), steatotic hepatocytes derived from hACE2 mice are more vulnerable to infection, as a result of increased expression of ACE2. Metformin, a common therapeutic option for hyperglycemia in type 2 diabetes (T2D) patients, prevents the interaction between the spike of SARS-CoV-2 and steatotic hepatocytes by reducing the expression of hACE2. In summary, we provide evidence that hepatocytes are amenable to SARS-CoV-2 infection and propose metformin as a therapeutic strategy to prevent liver dysfunction caused by SARS-CoV-2 in the context of NASH.

Upregulation of inflammatory genes and pathways links obesity to severe COVID-19

Project description:Obesity is a risk factor for developing severe COVID-19. However, the mechanism underlying obesity-accelerated COVID-19 remains unclear. Here, we report results from a study in which K18-hACE2 mice were fed an obesity-inducing western diet (WD) for over 3 months before intranasal infection with SARS-CoV2. After infection, the WD-fed K18-hACE2 mice lost more body weight and had more severe lung inflammation than normal chow (NC)-fed mice. Bulk RNAseq analysis of lungs and adipose tissue revealed that a diverse landscape of various immune cells, inflammatory markers, and pathways are upregulated in obese COVID-19 patients or the WD-fed K18-hACE2 mice when compared with their respective control groups. When compared with infected NC-fed mice in the lung, the infected WD-fed mice had upregulation of IL-6, a well-established marker for severe COVID-19. These results indicate that obesity-accelerated severe COVID-19 caused by SARS-CoV-2 infection in the K18-hACE2 mouse model can be used for dissecting the cellular and molecular mechanisms underlying pathogenesis. Furthermore, in the transcriptome analysis of the lung and adipose tissue obtained from deceased COVID-19 patients, we found upregulation of an array of genes and pathways associated with Inflammation. Both the K18-hACE2 mouse model and human COVID-19 patient data support a link between inflammation and an obesity-accelerated COVID-19 disease phenotype.

Illumina Human Polycystic Liver Disease and Normal Biliary Stem Cell RNAseq

Project description:Background & aims: Polycystic liver disease (PLD) is an autosomal dominantly inherited disorder caused by mutations in genes such as PRKCSH and SEC63. It has been thought that cysts develop from biliary progenitor cells due to loss-of-heterozygosity (LOH), leading to aberrant proliferation or defects in differentiation. Cyst expansion can be suppressed by somatostatin analogues such as lanreotide. There is no human in vitro model available that truly recapitulates polycystic liver disease. We hypothesize that PLD progenitors can form bipotent liver organoids that carry key features of cyst development. To find gene expression differences between Human Polycystic Liver Disease and Normal Biliary Stem Cells. Methods: Cells from normal biliary duct (n=6), cyst biliary epithelium (n=60) and cyst fluid (n=31) were isolated and placed under conditions suitable for expansion of human adult liver stem cells. We analyzed genetic LOH, gene expression, differentiation capacity, response to lanreotide and cilium formation of these organoids. Results: Cholangiocytes from cyst biliary epithelium (47/60) and cyst fluid (9/31) proved capable of expanding as bipotent liver organoids. Multiple cyst organoids displayed LOH surrounding PRKCSH or SEC63 regions. Organoids formed cilia when proliferation was inhibited. Neither hepatocyte nor biliary differentiation of PLD organoids was impaired. RNAseq revealed no significantly dysregulated pathway in PLD organoids. Lanreotide significantly decreased expansion of liver organoids in comparison to negative control (197% ± 46% versus 547% ± 28%; p: 0.038). Conclusion & discussion: Biliary progenitor cells from patient cyst epithelium and fluid can expand into liver organoids. They recapitulate key characteristics of PLD, and are a promising human in vitro model for research, diagnostics and treatment of polycystic liver diseases and cholangiociliopathies.
