Gene expression profile of macrophages of monocytic origin and Kupffer cells under conditions of co-cultivation with Ito cells, endotheliocytes of sinusoidal capillaries of the liver and HGF.

Project description:The aim of the work was to study the expression profile of Kupffer cells and macrophages of monocytic origin under conditions of co-cultivation with Ito cells, endotheliocytes of sinusoidal capillaries of the liver and HGF. To test the hypothesis that it is the microenvironment that forms the specific phenotype of resident organ macrophages. We used microarrays for comparison of Kupffer cells and macrophages of monocytic origin gene expression on different time periods of cocultivation with Ito cells, endotheliocytes of sinusoidal capillaries of the liver and HGF.

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.

Human liver sinusoidal endothelial cells support the development of functional human pluripotent stem cell-derived Kupffer cells

Project description:In mice, Kupffer cells (KCs) first derive from yolk sac (YS) hematopoietic progenitors prior to the emergence of the hematopoietic stem cell. To investigate human KC ontogeny, we recapitulated YS hematopoiesis from human pluripotent stem cells (hPSCs) and transplanted derivative macrophage progenitors into NSG mice previously humanized with hPSC-liver sinusoidal endothelial cells (LSECs). We demonstrate that hPSC-LSECs facilitate stable hPSC-YS-macrophage engraftment for at least 7 weeks. Single cell RNA sequencing of engrafted YS-macrophages revealed a homogenous MARCO-expressing KC gene signature and low expression of inflammatory macrophage genes. In contrast, human cord blood (CB)-derived macrophages generated grafts that contain multiple hematopoietic lineages in addition to KCs. Functional analyses showed that the engrafted KCs actively perform phagocytosis and erythrophagocytosis in vivo. Taken together, these findings demonstrate that it is possible to generate human KCs from hPSCs and show that the equivalent of the human YS hematopoietic programs represent enriched sources of progenitors for this lineage.

Next Generation Sequencing Facilitates Quantitative Analysis of HGF treated (HGF+) and matched control (HGF-) HepG2 cells

Project description:We report the high-throughput profiling of HGF treated liver cancer cell (HepG2) for differentiated genes analysis. We generated HGF stimulated and paired control HepG2 cells for 4 days. We find that tumor suppressor genes that are overexpressed and some tumor associated genes were downregulated, therefore reflect cell state and HGF induced anti-tumor potential. This study provides a potential framework for the research of HGF induced critical genes in the application of liver cancer therapy.

Liver-derived signals sequentially reprogram myeloid enhancers to initiate and maintain Kupffer cell identity (RNA-Seq)

Project description:Tissue environment plays a powerful role in establishing and maintaining the distinct phenotypes of resident macrophages, but the underlying molecular mechanisms remain poorly understood. Here, we characterized transcriptomic and epigenetic changes in repopulating liver macrophages following acute Kupffer cell depletion as a means to infer signaling pathways and transcription factors that promote Kupffer cell differentiation. We obtain evidence that combinatorial interactions of the Notch ligand DLL4 and transforming growth factor-b (TGF-?) family ligands produced by sinusoidal endothelial cells and endogenous LXR ligands were required for the induction and maintenance of Kupffer cell identity. DLL4 regulation of the Notch transcriptional effector RBPJ activated poised enhancers to rapidly induce LXR? and other Kupffer cell lineage-determining factors. These factors in turn reprogrammed the repopulating liver macrophage enhancer landscape to converge on that of the original resident Kupffer cells. Collectively, these findings provide a framework for understanding how macrophage progenitor cells acquire tissue-specific phenotypes.

Liver-derived signals sequentially reprogram myeloid enhancers to initiate and maintain Kupffer cell identity (ATAC-Seq)

Project description:Tissue environment plays a powerful role in establishing and maintaining the distinct phenotypes of resident macrophages, but the underlying molecular mechanisms remain poorly understood. Here, we characterized transcriptomic and epigenetic changes in repopulating liver macrophages following acute Kupffer cell depletion as a means to infer signaling pathways and transcription factors that promote Kupffer cell differentiation. We obtain evidence that combinatorial interactions of the Notch ligand DLL4 and transforming growth factor-b (TGF-β) family ligands produced by sinusoidal endothelial cells and endogenous LXR ligands were required for the induction and maintenance of Kupffer cell identity. DLL4 regulation of the Notch transcriptional effector RBPJ activated poised enhancers to rapidly induce LXRα and other Kupffer cell lineage-determining factors. These factors in turn reprogrammed the repopulating liver macrophage enhancer landscape to converge on that of the original resident Kupffer cells. Collectively, these findings provide a framework for understanding how macrophage progenitor cells acquire tissue-specific phenotypes.
