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

ABSTRACT: 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).

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.

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.

scRNAseq of isolated fetal liver erythroid progenitor cell subpopulations, and CITE-seq of mouse fetal liver erythroid progenitors

Project description:We used scRNAseq to profile CD71/CD24low fetal liver erythroid progenitor cells isolated by 2 distinct methods: FACS and immunomagnetic isolation. Cells from both isolation methods were hashtagged using Biolegend mouse hashtag antibodies and library prepped together on the 10X chromium platform with the 3'RNA v3 kit. We also performed CITE-seq to profile proteogenomic expression of CD117 and CD71 on lineage-depleted mouse fetal liver erythroid progenitor cells. CITE-seq was performed through a separate library prep on the 10X chromium platform with the 3'RNAv3 kit.

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).

Age of the bone marrow dictates clonality of smooth muscle-derived cells in the atherosclerotic plaque [bulk RNA-seq]

Project description:Purpose: The goal of this study is to investigate the gene expression in aged (18 month old) and young (3 month old) bone marrow-derived monocytes. Methods: Bone marrow was harvested by flushing the femurs and tibias of young (3 month old) and aged (18 month old) mice in PBS with 2% fetal bovine serum (FBS) on ice. Cells were isolated from bone marrow by density gradient centrifugation using Lympholyte (Cedarlane, CL0531). After centrifugation at 1300 g for 20 min, bone marrow cells were collected from the interface and washed in Ca2+/Mg2+ - free HBSS. The cells were dissociated to a single-cell suspension by filtering through a 70-µm nylon mesh. For monocyte isolation, a suspension of bone marrow cells was stained with Alexa 700 anti-CD3 (1:100, BioLegend, 100215), PE-Cy7 anti-CD19 (1:100, BioLegend, 115520), FITC anti-CD11b (1:100, BD Pharmingen, 553310) and APC anti-Ly6c antibodies (1:100, BioLegend, 128015) in PBS with 0.5% FBS for 30 min. CD11b+Ly6c+CD3-CD19- monocytes were isolated with a BD FACSAria cell sorter. Total RNA was extracted and subjected to bulk RNA-seq using Illumina HiSeq 2000. Results: Expression profiles of the transcriptome are compared between bone marrow-derived monocytes isolated from aged (18 month old) and young (3 month old) mice. Conclusions: Significant differences in the expression levels of genes are noted between the two age groups.

Feeder-Free Generation and Characterization of Endocardial and Cardiac Valve Cells from Human Pluripotent Stem Cells

Project description:Valvular heart disease presents a significant health burden, yet advancements in valve biology and novel therapeutics have been hindered by the lack of accessibility to human valve cells. In this study, we have developed a scalable and feeder-free method to differentiate human induced pluripotent stem cells (iPSCs) into endocardial cells. Importantly, we show that these endocardial cells are transcriptionally and phenotypically distinct from vascular endothelial cells and can be directed to undergo endothelial-to-mesenchymal transition (EndMT) to generate cardiac valve cell populations. Following this, we identified two distinct populations—one population undergoes EndMT to become valvular interstitial cells (VICs), while the other population reinforces their endothelial identity to become valvular endothelial cells (VECs). We then characterized our iPSC-derived cell populations and identified putative markers for these populations through bulk RNAseq transcriptome analyses. Lastly, we validated our VIC and VEC populations by comparing our transcriptomic data to pseudobulk data generated from single-cell RNAseq of normal valve tissue from a 15-week-old human fetus. By increasing the accessibility to these cell populations, we aim to accelerate discoveries for cardiac valve biology and disease.
