Abstract
The liver has excellent regeneration potential and attains complete functional recovery from partial hepatectomy. The regenerative mechanisms malfunction in chronic liver diseases (CLDs), which fuels disease progression. CLDs account for 2 million deaths per year worldwide. Pathophysiological studies with clinical correlation have shown evidence of deviation of normal regenerative mechanisms and its contribution to fueling fibrosis and disease progression. However, we lack realistic in vitro models that can allow experimental manipulation for mechanistic understanding of liver regeneration in CLDs and testing of candidate drugs. In this review, we aim to provide the framework for building appropriate organotypic models for dissecting regenerative responses in CLDs, with the focus on non-alcoholic steatohepatitis (NASH). By drawing parallels with development and hepatectomy, we explain the selection of critical components such as cells, signaling, and, substrate-driven biophysical cues to build an appropriate CLD model. We highlight the organoid-based organotypic models available for NASH disease modeling, including organ-on-a-chip and 3D bioprinted models. With the focus on bioprinting as a fabrication method, we prescribe building in vitro CLD models and testing schemes for exploring the regenerative responses in the bioprinted model.

Abstract
Spheroid cultures of primary human hepatocytes (PHH) are used in studies of hepatic drug metabolism and toxicity. The cultures are maintained under different conditions, with possible confounding results. We performed an in-depth analysis of the influence of various culture conditions to find the optimal conditions for the maintenance of an in vivo like phenotype. The formation, protein expression, and function of PHH spheroids were followed for three weeks in a high-throughput 384-well format. Medium composition affected spheroid histology, global proteome profile, drug metabolism and drug-induced toxicity. No epithelial-mesenchymal transition was observed. Media with fasting glucose and insulin levels gave spheroids with phenotypes closest to normal PHH. The most expensive medium resulted in PHH features most divergent from that of native PHH. Our results provide a protocol for culture of healthy PHH with maintained function - a prerequisite for studies of hepatocyte homeostasis and more reproducible hepatocyte research. 3D spheroid cultures were established in 384-well format Eight different media variants were used to optimize the 3D cultures Optimized William's medium was as good as expensive commercial medium The 3D cultures were used to study drug metabolism and toxicity

Abstract
The lack of robust methods to preserve, purify and in vitro maintain the phenotype of the human liver’s highly specialized parenchymal and non-parenchymal cell types importantly hampers their exploitation for the development of research and clinical applications. There is in this regard a growing interest in the use of tissue-specific extracellular matrix (ECM) to provide cells with an in vitro environment that more closely resembles that of the native tissue. In the present study, we have developed a method that allows for the isolation and downstream application of the human liver’s main cell types from cryopreserved material. We also isolated and solubilized human liver ECM (HL-ECM), analyzed its peptidomic and proteomic composition by mass spectrometry and evaluated its interest for the culture of distinct primary human liver cells. Our analysis of the HL-ECM revealed proteomic diversity, type 1 collagen abundance and partial loss of integrity following solubilization. Solubilized HL-ECM was evaluated either as a coating or as a medium supplement for the culture of human primary hepatocytes, hepatic stellate cells and liver sinusoidal endothelial cells. Whereas the solubilized HL-ECM was suitable for cell culture, its impact on the phenotype and/or functionality of the human liver cells was limited. Our study provides a first detailed characterization of solubilized HL-ECM and a first report of its influence on the culture of distinct human primary liver cells.

Abstract
High morbidity and mortality are associated with acute liver injury (ALI) for which no effective targeted drugs or pharmacotherapies are available. Discovery of potential therapeutic targets as well as inhibitors that can alleviate ALI is imperative. As excessive inflammatory cytokines released by macrophages are a critical cause of liver injury, we aimed to find novel compounds that could inhibit macrophage expression of inflammatory cytokines and alleviate liver injury. Methods: A high throughput assay was established to screen a small molecule inhibitor library of epigenetic targets. A highly selective catalytic p300/CBP inhibitor A-485 was identified as a potent hit in vitro and administrated to the lipopolysaccharide (LPS)/D-galactosamine (GalN)-induced mice in vivo. For in vitro analysis, RAW264.7 cells and primary BMDM cells exposed to LPS were co-incubated with A-485. A model of acute liver injury induced by LPS and GalN was used for evaluation of in vivo treatment efficacy. Results: A-485 inhibited LPS-induced inflammatory cytokine expression in a concentration-dependent manner in vitro. Significantly, A-485 administration alleviated histopathological abnormalities, lowered plasma aminotransferases, and improved the survival rate in the LPS/GalN-stimulated mice. Integrative ChIP-Seq and transcriptome analysis in the ALI animal model and macrophages revealed that A-485 preferentially blocked transcriptional activation of a broad set of pathologic genes enriched in inflammation-related signaling networks. Significant inhibition of H3K27ac/H3K18ac at promoter regions of these pivotal inflammatory genes was observed, in line with their suppressed transcription after A-485 treatment. Reduced expression of these pathological pro-inflammatory genes resulted in a decrease in inflammatory pathway activation, M1 polarization as well as reduced leukocyte infiltration in ALI mouse model, which accounted for the protective effects of A-485 on liver injury. Conclusion: Using a novel strategy targeting macrophage inflammatory activation and cytokine expression, we established a high-throughput screening assay to discover potential candidates for ALI treatment. We demonstrated that A-485, which targeted pathological inflammatory signaling networks at the level of chromatin, was pharmacologically effective in vivo and in vitro. Our study thus provided a novel target as well as a potential drug candidate for the treatment of liver injury and possibly for other acute inflammatory diseases.

Abstract
The murine CLEC4f gene encodes the Kupffer cell receptor, a galactose-binding receptor containing a C-type carbohydrate-recognition domain. Orthologs have been identified in nearly 100 species. The receptors from rat and mouse have previously been characterized and data presented here show that functional CLEC4f protein is expressed in domestic cattle (Bos taurus). However, the human CLEC4f gene does not encode a functional receptor because a mutation in the splice acceptor site of the final exon prevents appropriate splicing and a missense mutation disrupts the sugar-binding site. Transcriptomic and PCR analysis of transcripts confirms the absence of a spliced transcript containing the final exon and only background levels of transcripts are detected in human tissues. These mutations are also present in the CLEC4f gene in Neanderthals. In contrast to humans, closely related species, including chimpanzees, do have CLEC4f genes that encode full-length receptors. Affinity chromatography and glycan array results demonstrate that the chimpanzee, bovine and murine proteins all bind to galactose, but they show preferences for different subsets of galactose-containing glycans. In non-human primates, the receptor is expressed in spleen rather than in liver. The results indicate that the CLEC4f protein probably has distinct functions in different species. Absence of the receptor precludes using it for targeting of glycoconjugates to cells in human liver. The fact that CLEC4f protein is expressed in spleen in non-human primates and the close evolutionary relationship of the CLEC4f protein to langerin (CD207) suggest that it may function in the immune system, possibly as a pathogen receptor.

Abstract
BACKGROUND Piwi-interacting RNA (piRNA) is the largest class of small non-coding RNA, which has also been identified in somatic tissues, and aberrant expression of piRNAs in tumor tissues may be implicated in carcinogenesis. piR-823 is increased in liver cirrhosis and hepatocellular carcinoma (HCC). However, there is no report on the function of piR-823 in hepatic stellate cells (HSCs) activation during hepatic fibrosis. The present study investigated the role of piR-823 in HSC activation. MATERIAL AND METHODS Liver fibrosis was induced in mice by carbon tetrachloride (CCL4) injection and bile duct ligation (BDL). The primary HSCs were isolated from mice and cultured. The expression of piR-823 was measured by real-time PCR. The effect of piR-823 on HSCs was evaluated by either sense sequence or antisense sequence of piR-823 carried by liposome. Proteins binding to piR-823 were assayed by RNA pull-down technique and liquid chromatography-mass spectrometry (LC-MS). RESULTS Our data for the first time show that piR-823 is significantly upregulated in activated HSCs. Overexpression of piR-823 promoted HSC proliferation, α-SMA and COL1a1 production, whereas inhibition of piR-823 suppressed the activity of HSCs. Interestingly, the combination of piR-823 and EIF3B promoted TGF-β1 expression. CONCLUSIONS Our data illustrate a novel mechanism of piR-823 in HSC activities. The combination of piR-823 and EIF3B increased TGF-β1 expression, which activates HSCs in liver fibrosis. piR-823 may be a new target in the treatment of liver fibrosis.

Abstract
Co-cultivation of tumor cells and liver resident immune cells or other non-parenchymal cells (NPCs) from the same donor is important for the study of cancer metastasis. So far, little is known about the mechanism of tumor cell or pathogen clearance, leukocyte infiltration, and immune cell recruitment in the human liver. To investigate these processes in vitro, the use of primary human hepatocytes and non-parenchymal cell, especially immune cell, co-culture systems play essential roles in the establishment of cell-cell and cell-extracellular matrix communications similar to native liver tissues. Hepatic non-parenchymal cells mainly comprise liver sinusoid endothelial cells (LSECs), microvascular endothelial cells, hepatic stellate cells, Kupffer cells (KCs), natural killer T (iNKT) cells, and dendritic cells (DCs). Here we describe procedures for preparation, isolation, and culture of human liver resident immune cells and other non-parenchymal cells. © 2018 by John Wiley & Sons, Inc.

Abstract
The hepatic stellate cells (HSCs) localize at the space of Disse in the liver and have multiple functions. They are identified as the major contributor to hepatic fibrosis. Significant understanding of HSCs has been achieved using rodent models and isolated murine HSCs; as well as investigating human liver tissues and human HSCs. There is growing interest and need of translating rodent study findings to human HSCs and human liver diseases. However, species-related differences impose challenges on the translational research. In this review, we focus on the current information on human HSCs isolation methods, human HSCs markers, and established human HSC cell lines.
