RNAseq analysis of bone marrow endothelial cells

ABSTRACT: 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.

Single-cell transcriptome Atlas reveals embryonic endothelial heterogeneity

Project description:Mature endothelial cells (ECs) are heterogeneous, with subtypes defined by tissue origin and by position within the vascular bed. Here, we performed scRNA-seq with mouse embryonic ECs and identified 19 subclusters, including Etv2+Bnip3+ early EC progenitors. Most of these subtypes were grouped by their vascular-bed types, while ECs from brain, heart and liver were grouped by their tissue origins. Compared to arterial ECs (aECs), embryonic venous (vECs) and capillary ECs (cECs) shared less markers with their adult counterparts. cECs showed some venous characteristics. One cEC cluster with both venous and capillary features served as a branch point for aEC and vEC lineages. aECs and vECs showed distinct transcriptional regulatory networks.

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.

DNA Methylation Profiles of Airway Epithelial Cells and PBMCs from Healthy, Atopic and Asthmatic Children.

Project description:DNA methylation profiling of airway epithelial cells (AECs) and peripheral blood mononuclear cells (PBMCs) from normal, atopic and asthmatic subjects. The Illumina GoldenGate Methylation Cancer Panel I was used to obtain DNA methylation profiles across approximately 1505 CpGs in AECs and PBMCs. Samples included 7 healthy, 9 atopic, 4 atopic asthmatic and 5 non-atopic asthmatic subjects. Please note that only some of the samples are matched (i.e. AECs and PBMCs from the same individual) due to DNA quality or sample collection (i.e. only one sample (AEC or PBMC) was collected from the patient). Bisulphite converted DNA from the 41 samples were hybridised to the Illumina GoldenGate Methylation Beadchip

Expression data from developing mouse livers

Project description: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).

AEC II cell differentiation in miR142 overexpressing mice

Project description:We observed that loss of miR142 leads to the increased expression of surfactant protein C and decreased Podoplanin. This indicates increased differentiation of alveolar progenitors towards AEC II lineage. In order to understand what are the genes that are being regulated during AEC II cell differentiation in miR142 overexpressing mice we are performing this experiment.

Gene expression analysis of airway epithelial cells exposed to flagellin via microarray

Project description:Airway epithelial cells (AEC) are critical components of the inflammatory and immune response during exposure to pathogens. AECs in monolayer culture and differentiated epithelial cells in air-liquid interface (ALI) represent two distinct and commonly used in vitro models, yet differences in their response to pathogens have not been investigated. In this study, we compared the transcriptional effects of flagellin on AECs in monolayer culture versus ALI culture using exon microarrays and RNAsequencing. We found that AECs cultured in monolayer and ALI have strikingly different transcriptional states at baseline. When challenged with flagellin, monolayer AEC cultures greatly increased transcription of numerous genes mapping to wounding response, immunity and inflammatory response. In contrast, AECs in ALI culture had an unexpectedly muted response to flagellin, both in number of genes expressed and relative enrichment of inflammatory and immune pathways. In conclusion, In vitro culturing methods have a dramatic effect on the transcriptional profile of AECs at baseline and after stimulation with flagellin. These differences suggest that epithelial responses to pathogen challenges are distinctly different in culture models of intact and injured epithelium.

Human Feto-placental Arterial and Venous Endothelial Cells are Differentially Programmed by Gestational Diabetes Mellitus Resulting in Cell-specific Barrier Function

Project description:We performed genome-wide methylation analysis of primary feto-placental arterial and venous endothelial cells from healthy (AEC and VEC) and GDM complicated pregnancies (dAEC and dVEC). Parallel transcriptome analysis identified variation in gene expression linked to GDM-associated DNA methylation, implying a direct functional link. Pathway analysis found that genes altered by exposure to GDM clustered to functions associated with ’Cell Morphology’ and ’Cellular Movement’ in both AEC and VEC. Further functional analysis demonstrated that GDM exposed cells have altered actin organization and barrier function. Our data indicate that exposure to GDM programs atypical morphology and barrier function in feto-placental endothelial cells by DNA methylation and gene expression change. The effects differ between AEC and VEC, indicating a stringent cell-specific sensitivity to adverse exposures associated with developmental programming in utero.
