Qualifying a human Liver-Chip for predictive toxicology: Performance assessment and economic implications

ABSTRACT: We assess RNA expression in human primary hepatocytes in Vials Day 0 and Liver-Chips on Day 3 and Day 7 for two different donors. The hepatocytes were co-cultured in Liver-Chip model with Kupffer cells and Liver sinusoidal endothelial cells (LSECs) and stellate cells .

Transcriptomic Analysis of Hepatic Cells in Multicellular Organotypic Liver Models

Project description:In this study, genome-wide gene expression profiles of primary hepatocytes and liver sinusoidal endothelial cells (LSECs) were measured at day 12 for each cell culture system using Affymetrix GeneChips and analyzed via Gene Set Enrichment Analysis (GSEA). The culture systems analyzed include the commonly used collagen sandwich and monolayers of hepatocytes, as well as 3-dimensional (3D) engineered liver models that contain hepatocytes and LSECs (3DHL) and hepatocytes, LSECs, and Kupffer cells (3DHLK). Our results highlight the up-regulation of several hepatocyte specific functions in hepatocytes and a novel interplay between Ppara signaling and bile acid biosynthesis in LSECs.

Genome-wide transcriptome profiling of human Liver-Chip model of alcohol-associated liver disease (ALD) using RNA-seq.

Project description:The goal of this study was to assess RNA expression in human primary hepatocytes in response to ethanol exposure compared to control. The hepatocytes were cultured in co-culture on a Liver-Chip model with Kupffer cells and Liver sinusoidal endothelial cells (LSECs) and treated with 0.08% to 0.16% ethanol for 48h.

Transcriptome of human liver cells and culture-activated hepatic stellate cells

Project description:The molecular determinants of a healthy human liver cell phenotype remain largely uncharacterized. In addition, the gene expression changes associated with activation of primary human hepatic stellate cells, a key event during fibrogenesis, remain poorly characterized. Here, we provide the transriptomic profile underpinning the healthy phenotype of human hepatocytes, liver sinusoidal endothelial cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as activated HSCs (aHSCs) We assess the transcriptome for purified, non-cultured human hepatocytes, liver sinusoidal cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as culture-activated HSCs (aHSCs). Hepatocytes (n=2 donors), LSECs (n=3), qHSCs (n=3) and in vitro activated HSCs (n=3; from the same donors as the qHSCs and LSECs) were used for this study.

Genome-wide analysis of DNA methylation and gene expression patterns in purified, uncultured human liver cells and activated hepatic stellate cells

Project description:The human liver contains multiple cell types whose epigenetic patterns are undetermined. We examined the promoter methylome of purified and uncultured hepatic stellate cells (HSCs), hepatocytes (HEPs) and liver sinusoidal endothelial cells (LSECs), by methylated DNA immunoprecipitation (MeDIP) and array hybridization. Uncultured HSCs, LSECs and Heps show ~7000-8000 methylated promoters, with 60-70% similarity between all cell types. GO analysis for commonly methylated genes reveals involvement in germ cell development, segregating germ-line from somatic lineage methylation. HSCs, LSECs and HEPs also contain ~500-1000 uniquely methylated promoters; these are implicated in signaling and biosynthetic processes (HSCs), lipid transport and metabolism (LSECs), and chromatin assembly (HEPs). The promoter methylome of culture-activated HSCs deviates from that of their uncultured (quiescent) counterparts. HSC culture-induced activation also enhances methylation differences between individual donors; however this does not necessarily relate to changes in gene expression. HSc activation results in a net gain of promoter DNA methylation, despite the demethylation and de novo methylation of thousands of promoters. Our data provide to our knowledge the first genome-wide maps of promoter DNA methylation in human purified and uncultured liver cell types. Although methylation profiles are largely similar between HSCs, LSECs and hepatocytes, the detection of cell type-specific methylation patterns suggests a differential epigenetic programming of these cell types in the liver. Determine the promoter DNA methylation pattern of 3 uncultured, reshly isolated, human healthy liver cell types (hepatocytes (HEPs), liver sinusoidal endothelial cells (LSECs) and haptic stellate cells (HSCs), and of HSCs after a 24-h culture-induced activation.

Freshly isolated rat liver sinusoidal endothelial cells and Kupffer cells, LC-MSMS

Project description:Liver sinusoidal endothelial cells (LSECs) and Kupffer cells (KCs) have important roles in liver homeostasis and host defense. Sharing the same microenvironment in the liver sinusoid, they form an effective scavenger cell system for removal of potentially harmful blood-borne substances. Unlike most other endothelia, LSECs are highly efficient in endocytosis of nanoparticles, including virus. Though controversial, LSECs have been reported to act as antigen presenting cells, thus contributing importantly to induction of immune tolerance in liver. There are also controversies about LSEC and KC specific markers, which may be due to overlapping cell functions, species differences, and/or problems with cell purification. We therefore used label-free proteomics to characterize and quantitatively compare proteome of freshly isolated, highly pure rat LSECs (SE-1/CD32b positive) and KCs (CD11b/c positive.We found that most immune genes expressed in KCs were also expressed in LSECs, albeit at a lower density, and they also have overlap in cell surface marker expression. Both cell types express high levels of scavenger receptors and immune lectins.
