Transcriptional Dynamics of Hepatic Sinusoid-Associated Cells After Liver Injury [bulk RNA-seq]

ABSTRACT: Here we profile the transcripts of app. 35.000 single cells isolated from livers of healthy and diseased mice. We show the transcriptomic change associated with fibrosis induction in the non-parenchymal cell types (hepatic stellate cells, liver endothelial cells and macrophages). We reveal a hitherto unknown feature of the HSCs otherwise functionally attributed to the LECs.

Single cell-resolved study of advanced murine MASH reveals a homeostatic pericyte signaling module

Project description:Here we profile the transcripts of app. 32.000 single cells isolated from livers of healthy mice fed with a chow diet and diseased mice fed with a western diet for 52 weks. We analyzed the fibrogenic transition of HSCs from pericytes to collagen-producing cells, interrogated the NASH-associated rerouting of mononuclear phagocytes and uncovered novel aspects of cellular palsticity during more advanced stages of NASH. We reveal Stellate cell-specific Gs-protein-coupled receptors and the bile-acid receptor NR1H4/FXR seemingly dominated HSC biology in the healthy liver, forming the basis for multimodal diurnal signaling, but deteriorated in activated HSCs in advanced NASH. In addition to two emerging populations of Trem2-expressing monocyte-derived macrophages we found a population of CD207-positive macrophages significantly expanded in advanced NASH and likely derived from both incoming monocytes and Kupffer cells. Our work illustrates the emmense plasticity liver cells undergo upon induction of NASH, and potentially map novel treatment targets

Gene expression profiling and secretome analysis differentiate Adult-Derived Human Liver Stem/progenitor Cells and human hepatic stellate cells

Project description:Adult-derived human liver stem/progenitor cells (ADHLSC) are obtained after primary culture of the liver parenchymal fraction. The cells are of fibroblastic morphology and exhibit a hepato-mesenchymal phenotype. Hepatic stellate cells (HSC) derived from the liver non-parenchymal fraction present a comparable morphology as ADHLSC. Because both ADHLSC and HSC are described as liver stem/progenitor cells, we strived to extensively compare both cell populations at different levels and to propose tools demonstrating their singularity. The database include full expression (HGU-219) measurements samples from 7 Adult-Derived Human Liver Stem/progenitor (n=7) and human hepatic stellate samples (n=7)

Human liver cells proteome

Project description:The human liver functions through a complex interplay of parenchymal and non-parenchymal cells, which participate in performing many essential aspects of metabolism and secretion. Mass spectrometry-based proteomic analysis of intact tissue has improved the understanding of these processes, by providing an in-depth view of the human liver proteome. However, the predominance of parenchymal cells, i.e. hepatocytes, means that the total tissue proteome mainly reflects hepatocyte expression. In this study, we therefore used quantitative label-free proteomic analysis to analyze the proteomes of the major parenchymal and non-parenchymal cell types in the human liver, i.e. hepatocytes, liver sinusoidal endothelial cells, Kupffer cells, and hepatic stellate cells. We found that our data recapitulated specific functional differences between cell types, meaning that it can be used to reliably probe various aspects of cellular interplay. Thus, the data we provide constitutes a unique resource for exploring the human liver proteome at major cell type resolution.

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.

Transcriptional profiling of hepatic stellate cells (HSCs) isolated from Western diet/high fructose-fed C57BL6/J mice, carbon tretrachloride (CCl4)-treated C57BL6/J mice, and of murine HSCs differentiated in vitro

Project description:Hepatic stellate cells are involved in the development of hepatic fibrosis. We here perform transcriptional profiling of hepatic stellate cells (HSCs) isolated from Western diet/high fructose-fed C57BL6/J mice, carbon tretrachloride (CCl4)-treated C57BL6/J mice, and of murine HSCs differentiated in vitro. Specifically, gene expression profiles are obtained from hepatic stellate cells isolated from C57BL6 mice fed a Western Diet supplemented with high fructose for 12, 16 or 24 weeks or normal chow. From hepatic stellate cells isolated from C57BL6 mice treated CCl4 for 1, 4 or 8 weeks or treated with vehicle. From hepatic stellate cells isolated from healthy C57BL6 mice and seeded on normal plastic cell culture dishes for 1, 4, 8, or 12 days. And from hepatic stellate cells isolated from healthy C57BL6 mice and seeded on normal plastic cell culture dishes for 6 days in the presence of 10uM U0126 or DMSO.

Identification of the proteins secreted by normal and cirrhotic LSECs

Project description:Normal and cirrhotic LSECs can influence hepatic stellate cells (HSCs) differently. This project aims to determine the set of proteins secreted by LSECs from healthy and cirrhotic livers, and identify the protein(s) that promote HSC activation.

Expression data from HSCs

Project description:Hepatic stellate cells (HSCs) experience phenotypic transformation, from the quiescent phenotype to the activated one, after different etiologies of liver injury. Liver fibrosis is then occurred upon the activation of HSCs. miR-16 deficiency is identified to be an important characteristic of HSCs activation. We used Affymetrix rat 230 2.0 arrays (Affymetrix, Santa Clara, U.S.A.) to uncover the global alternations of transcriptome under miR-16 restoration. We isolated quiescent hepatic stellate cells (HSCs) from adult male SD rats (normal control group) by in situ perfusion and density-gradient centrifugation. Activated HSCs were separated from rats of fibrosis model group, which were treated by 40% carbon tetrachloride (CCl4) for 8 weeks, by means of liver section, digestion and sequential centrifugation. Quiescent and activated HSCs were then divided into 4 groups at random, namely quiescent HSCs, activated HSCs, pLV-miR-16-treated HSCs and pLV-GFP-treated HSCs. The pLV-miR-16-treated group, pLV-GFP-treated group were infected with pLV-miR-16 and pLV-GFP, respectively.

Integrative gene expression profiling analysis of human quiescent hepatic stellate cells

Project description:Unveiling the regulatory pathways maintaining hepatic stellate cells (HSC) in a quiescent (q) phenotype is essential to develop new therapeutic strategies to treat fibrogenic diseases. To uncover the miRNA-mRNAs regulatory interactions in qHSCs, HSCs were FACS-sorted from healthy livers and activated HSCs were generated in vitro. MiRNA Taqman array analysis showed HSCs expressed a low number of miRNA, from which 46 were down-regulated and 212 up-regulated upon activation. Computational integration of miRNA and gene expression profiles revealed that 66% of qHSCs miRNAs correlated with more than 6 altered targeted mRNAs (17,28Â±10,7 targets/miRNA), whereas aHSC-associated miRNAs had an average of 1,49 targeted genes. Interestingly, interaction networks generated by miRNA-targeted genes in qHSCs were associated with key HSCs activation processes. Next, selected miRNAs were validated in healthy and cirrhotic human livers and miR-192 was chosen for functional analysis. Down-regulation of miR-192 in HSC was found to be an early event during fibrosis progression in mouse models of liver injury. Moreover, mimic assays for miR-192 in HSCs revealed its role in HSC activation, proliferation and migration. Together, these results uncover the importance of miRNAs in the maintenance of qHSC phenotype and form the basis for understanding the regulatory networks in HSCs. Transcriptomic profile derived from four quiescent hepatic stellate (QHSC), four activated hepatic stellate (AHSC), three liver sinusoidal endothelial (LSEC) and two hepatocytes cells (HEP).
