Expression data from developing mouse livers

ABSTRACT: Roles of mesothelial cells (MCs) are poorly understood during liver development and injury. We identified podoplanin (Pdpn) as a cell surface markers for mesothelial cells in E12.5 mouse developing liver. To identify genes uniquely expressed in MCs, we isolated MCs from E12.5 mouse livers by FACS using anti-Pdpn antibodies and performed microarray analysis. The E12.5 liver was digested with trypsin-EDTA and incubated with antibodies against Pdpn. MCs were isolated as Pdpn+ population by FACS. Total RNA was extracted with RNAqueous Micro (Ambion) and the probes for the microarray were synthesized using the Ovation RNA amplification system V2 and FL-Ovation cDNA Biotin module V2 (Nugen). The labeled probes were hybridized with GeneChip Mouse Genome 430 2.0 arrays (Affymetrix) and signals were analyzed with Genomic Suite software (Partek).

Mesothelial cells give rise to hepatic stellate cells and myofibroblasts via mesothelial-mesenchymal transition in liver injury.

In many organs, myofibroblasts play a major role in the scarring process in response to injury. In liver fibrogenesis, hepatic stellate cells (HSCs) are thought to transdifferentiate into myofibroblasts, but the origins of both HSCs and myofibroblasts remain elusive. In the developing liver, lung, and intestine, mesothelial cells (MCs) differentiate into specific mesenchymal cell types; however, the contribution of this differentiation to organ injury is unknown. In the present study, using mous ...[more]

Expression data of mesenchymal cells from mouse liver

Project description:There are a few markers available to distinguish hepatic stellate cells (HSCs), portal fibroblasts (PFs), and mesothelial cells (MCs) in the adult mouse liver. To identify genes uniquely expressed in these cells, we isolated HSCs having Vitamin A lipids by FACS based on their autofluorescence. We isolated a mixed population containing PFs and MCs as Vitamin A lipid-negative and GFP-positive cells by FACS from Collagen1a1 promoter-driven GFP transgenic mice. MCs were isolated by FACS using anti-GPM6A antibodies from adult mouse livers. PFs were isolated by FACS as Vitamin A lipid-negative, GFP-positive, and GPM6A-negative cells. We also isolated HSCs, MCs, and PFs from Collagen1a1 promoter-driven GFP transgenic mouse livers having biliary fibrosis by FACS. Biliary fibrosis was induced by bile duct ligation for 3 weeks. Sham operation was performed as a control. After separation of these cells, we isolated total RNAs and analyzed mRNA expression by microarray analysis. Total RNA was extracted with RNAqueous Micro (Ambion) and the probes for the microarray were synthesized using the Ovation RNA amplification system V2 and FL-Ovation cDNA Biotin module V2 (Nugen). The labeled probes were hybridized with GeneChip Mouse Genome 430 2.0 arrays (Affymetrix) and signals were analyzed with Genomic Suite software (Partek).

Transcription as a function of tissue environment

Project description:We are interested in whether fibroblasts (CD45-CD31-Epcam-PDPN+PDGFRA+) cells exhibit unique transcriptional profiles. To this end, we digested tissues and FACS sorted CD45-CD31-Epcam-PDPN+PDGFRA+ fibroblasts CD45-CD31-Epcam-PDPN+PDGFRA- mesothelial cells and compared the transcriptional profiles of these cells.

Expression data from fetal and adult mouse liver mesothelial cells

Project description:Characterization and Functional Analyses of Hepatic Mesothelial Cells in Mouse Liver Development. We used microarrays to detail the global programme of gene expression in mesothelial cells during mouse liver development. Mouse liver mesothelial cells were selected by a cell sorter at E12.5 and adult for RNA extraction and hybridization on Affymetrix microarrays. We obtained PCLP1+ cells and Mesothelin+ cells at each developmental stage in order to analyze expression profiles of mesothelial cells.

RNAseq analysis of bone marrow endothelial cells

Project description:Although endothelial cells (ECs) have been shown to contribute to HSC maintenance in bone marrow (BM), differential contributions of EC subtypes remain unknown, owing to the lack of methods to separate with high purity arterial (AEC) from sinusoidal (SEC) endothelial cells. We show that combination of podoplanin (PDPN) and Sca-1 expression distinguishes AEC from SEC where Sca1brightPDPN—CD45—Ter119— cells exhibit an arterial gene signature and PDPN+Sca1dimCD45—Ter119— marks sinusoids. PDPN can be substituted for antibodies against the adhesion molecules ICAM1 or E-selectin that also mark SEC. We performed functional analysis of these different types of endothelial cells and found that SCF secreated from AECs regulate HSCs.

Gene expression data of nasopharyngeal carcinoma (NPC) cell and Podoplanin (PDPN) siRNA treatment

Project description:Podoplanin, a transmembrane sialomucin-like glycoprotein, is now widely used as a marker for lymphatic endothelial cells and fibroblastic reticular cells in lymphoid organs, but its study in nasopharyngeal carcinoma (NPC) is still limited. The aims of this study were t characterize the role of PDPN in NPC. Our results showed that PDPN was expressed in most TW01 NPC cells. PDPN knockdown by siRNA decreased NPC cell proliferation, migration, and invasion. Knocking down PDPN results in suppression of NPC cell proliferation, migration, and invasion. PDPN may serve as a potential chemotherapeutic target for NPC treatment in the future.

Osr1-mediated mesothelial transition of liver mesenchymal cells exacerbates fibrotic liver damage

Project description:In chronic liver diseases, hepatic stellate cells (HSCs) are induced to form the myofibroblasts responsible for scar formation, leading to liver fibrosis and cirrhosis. Here, single-cell RNA sequencing with in vivo lineage tracing in non-alcoholic steatohepatitis (NASH) model mice reveals a subpopulation of HSCs transitioning back to a state resembling their developmental precursors, mesothelial cells (MCs), after liver injury. These damage-associated intermediates between HSCs and MCs (DIHMs) can be traced with a dual recombinase system by labeling Krt19-expressing cells within pre-labeled Pdgfrb-positive HSCs, and DIHMs highly express inflammation- and fibrosis-associated genes. Cre and Dre-inducible depletion of DIHMs by administering diphtheria toxin reduces liver fibrosis and alleviates liver damage in NASH model mice. Importantly, knockdown of Osr1, a zinc finger transcription factor of the OSR gene family, can block DIHM induction in vitro. Conditional knockout Osr1 in Pdgfrb-expressing mesenchymal cells in NASH model mice can reduce liver fibrosis in vivo. Our study collectively uncovers an injury-induced developmental reversion process wherein HSCs undergo what we term a mesenchymal-to-mesothelial transition (MMesoT), which can be targeted to develop interventions to treat chronic liver diseases.

Genome-wide analysis of TRA (tissue restricted antigen)-specific co-expression groups in mouse medullary thymic epithelial cells (mTECs)

Project description:Analysis of gene co-expression patterns in TRA-specific medullary thymic epithelial cell (mTEC) subsets. The whole genome gene signatures of purified mTEC subsets respectively positive for the TRAs Gp2, Pdpn, Cea1, Gad1, Ins2, Tspan8 were compared to their corresponding TRA-negative mTEC subset control. Results provide the enriched and depleted gene expressions in the different subsets. Total RNA obtained from FACS isolated mTECs positive for the respective TRAs were compared to their TRA-negative mTEC subsets using specific antibodies (Pdpn, Gp2, Cea1, Tspan8) or reporter mice (Gad1, Ins2).
