Transcription profiling of rat aortic and endocardial endothelial cells

ABSTRACT: Endocardial (EE) and Aortic (AE) endothelial cells were isolated from the same two rats, pooled (EE and AE kept separately) and cultured for 2 passages. Culture conditions and confluence of EE and AE cell cultures were kept as identical as possible. RNA was isolated and the expression profile of both endothelial cell types was compared using the Affymetrix rat genome U34A array.

In addition to a number of common features, cardiovascular endothelium displays structural, functional, and genetic differences according to its position in the cardiovascular tree. In the heart, endocardial and cardiac microvascular endothelia (CMVE) interact directly with surrounding cardiomyocytes, whereas the endothelium within blood vessels interacts with smooth muscle cells. In this study, we investigated whether cardiac endothelial cells were distinct from aortic endothelial (AE) cells at ...[more]

Protein profiling of Aortic-Valvular and Endocardial endothelial cells using label-free proteomics

Project description:The variations in the protein profile of aortic-valvular (AVE) and endocardial endothelial (EE) cells are currently unknown. The current study's objective is to identify differentially expressed proteins and associated pathways in both endothelial cells. We used endothelial cells isolated from the porcine aortic valve and endocardium for the profiling of proteins. Label-free proteomics was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our proteomics analysis revealed that 29 proteins were highly expressed, and 25 proteins were less represented in the valve than endocardial endothelium. The first part of the study was already available in the ProteomeXchange Consortium (PXD009194).

Label-free quantitative Proteomics Analysis Reveals Distinct Molecular characteristics in Endocardial Endothelium

Project description:Endocardial endothelium, which lines the chambers of the heart, is distinct in its origin, structure, and function. However, though functionally very important, no studies at protein level have been conducted so far characterizing endocardial endothelium. In this study, we used endothelial cells from pig heart to investigate if endocardial endothelial cells are distinct at the proteome level. Using a high throughput liquid chromatography-tandem mass spectrometry for proteome profiling and expression, we identified sets of proteins that belong to specific biological processes and metabolic pathways in endocardial endothelial cells supporting its specific structural and functional roles.

BMP10 signaling promotes the development of endocardial cells from human pluripotent stem cell-derived cardiovascular progenitors

Project description:We established a differentiation strategy to generate endocardial-like cells from hPSCs. Endocardial-like cells generated from our protocol display major functional properties of endocardium in developing embryo: they can induce trabecular markers in early hPSC-derived ventricular cardiomyocytes and they can undergo endothelial-to-mesenchymal-trasition under appropriate conditions. Furthermore, the transcriptome of our in vitro generated endocardial cells showed a very high level of correlation to that of primary fetal endocardial cells. Functional properties and transcriptional profile of hPSC-derived endocardial cells were also compared to those of control (non-endocardial) endothelial cells. For scRNA-seq analysis live cells from bulk endocardial and control endothelial differentiation cultures were labeled with two different sets of anti-human Hashtag antibodies before sequencing. Single cell RNA sequencing was carried out on a sample consisting of 85% bulk endocardial cells (TotalSeq-A0255 anti-human Hashtag 5 antibody, BioLegend) and 15% bulk control endothelial cells (TotalSeq-A0254 anti-human Hashtag 4, Biolegend).

Regional differences in left ventricular shear stress contribute to heterogenity of the endocardial transcriptome

Project description:The role of shear stress, the frictional force of blood flow, on the endothelium has been well documented. Differences in shear stress can have profound effects on endothelial and blood vessel biology. Endothelial cells (ECs), termed endocardial ECs, line the heart chambers and are exposed to complex shear stress patterns. While it has been demonstrated that shear stress is important for heart development, little has been shown on the role of shear stress on adult ECs. 4D-MRI studies demonstrate regional differences in blood residence time. We sought to determine the effect of regional differences in endocardial shear stress on the endocardial transcriptome using RNA sequencing (RNA-seq) on 3 different regions (apex, mid-ventricle, outflow tract) from 8 adult pigs, for a total of 24 RNA-seq assays.

Next Generation Sequencing Facilitates Quantitative Analysis of Human Pluripotent Stem Cell-Derived Endocardial-like And Primary Cardiac Endothelial Cell Transcriptomes

Project description:Next-generation sequencing (NGS) has significantly advanced the elucidation of developmental signaling mechanisms that are important for different cell lineage formation from human pluripotent stem cells (hPSCs). We report here the application of RNA-sequencing technology for transcriptome profile of human primary cardiac microvascular endothelial cells and hPSC-derived endocardial endothelial cells, and compare to those of other cell lineages including hPSCs, mesoderm, cardiomcyotyes as well as mouse cardiac microvascular and endocardial endothelial cells. Six cardiac endothelial cell samples from two different hPSC lines and one donor were performed in IIIumina HiSeq2500. The resulting sequence reads (about 20 million reads per sample) were mapped to human genome (hg19) using HISAT, and the RefSeq transcript levels (RPKMs) were quantified using the python script rpkmforgenes.py. Our RNA-seq data confirmed the stable expression of key endocardial endothelial cell markers including CDH5, vWF, PECAM1, NFATC1 and NPR3, and the gene set enrichment analysis (GSEA) showed enrichment in angiogenesis and vasculature development. Hierarchical clustering of differentially expressed genes uncovered several as yet uncharacterized genes that may contribute to endocardial function. This study represents the first detailed analysis of endocardial-like endothelial cell transcriptomes generated by RNA-seq technology, providing insight into the mechanisms underlying the differentiation of hPSCs into endocardium.

Expression of human aortic endothelial cells treated with or without oxidized phospholipids (II)

Project description:Oxidized phospoholipids are a pro-inflammatory component of minimally modified lipoproteins that get trapped in the subendothelial space of atherosclerotic plaques of large arteries. To model the response of endothelial cells in a pro-atherosclerotic enviroment we measured the expression in primary endothelial cells with and without treatment with oxidized phsopolipids from 96 genetically identical donors of anonymous origin. These samples are an extention of samples of similar origin deposited in GSE20060 Primary human aortic endothelial cells were collected from aortic heart explants of heart transplant donors and cultured in standard cell culture condiditions. At confluence, cells were treated with or without 40 ug/ml oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphatidylcholine (Ox-PAPC) for 4 hours in media 199 containing 1% fetal bovine serum. After 4 hours, the cells were collected for RNA extraction and quantification of transcripts via microarrays. Application of electronic probe mask (HT_U133Amsk.cdf) on raw data.

Endocardial/endothelial angiocrines regulate cardiomyocyte development and maturation and induce features of ventricular non-compaction

Project description:Non-compaction cardiomyopathy is a devastating genetic disease caused by insufficient consolidation of ventricular wall muscle that can result in inadequate cardiac performance. Despite being the third most common cardiomyopathy, the mechanisms underlying the disease, including the cell types involved, are poorly understood. We have previously shown that endothelial cell-specific deletion of the chromatin remodeller gene Ino80 results in defective coronary vessel development that leads to ventricular non-compaction in embryonic mouse hearts. Here, we used single-cell RNA-sequencing to characterize endothelial and endocardial defects in Ino80-deficient hearts. We observed a pathological endocardial cell population in the non-compacted hearts and identified multiple dysregulated angiocrine factors that dramatically affected cardiomyocyte behaviour. We identified Col15A1 as a coronary vessel-secreted angiocrine factor, down-regulated by Ino80-deficiency, which functioned to promote cardiomyocyte proliferation. Furthermore, mutant endocardial and endothelial cells (ECs) AQ6 up-regulated expression of secreted factors, such as Tgfbi, Igfbp3, Isg15, and Adm, which decreased cardiomyocyte proliferation and increased maturation. These findings support a model where coronary ECs normally promote myocardial compaction through secreted factors, but that endocardial and ECs can secrete factors that contribute to non-compaction under pathological conditions.
