Project description:The identification of circulating endothelial progenitor cells has led to speculation regarding their origin as well as their contribution to neovascular development. Two distinct types of endothelium make up the blood and lymphatic vessel system. However, it has yet to be determined whether there are distinct lymphatic-specific circulating endothelial progenitor cells. We isolated circulating endothelial colony forming cells (ECFCs) from whole peripheral blood. These cells are endothelial in nature, as defined by their expression of endothelial markers and their ability to undergo capillary morphogenesis in three-dimensional culture. A subset of isolated colonies express markers of lymphatic endothelium, including VEGFR-3 and Prox-1, with low levels of VEGFR-1, a blood endothelial marker, while the bulk of the isolated cells express high VEGFR-1 levels with low VEGFR-3 and Prox-1 expression. The different isolates have differential responses to VEGF-C, a lymphatic endothelial specific cytokine, strongly suggesting that there are lymphatic specific and blood specific ECFCs. Global analysis of gene expression revealed key differences in the regulation of pathways involved in cellular differentiation between blood and lymphatic-specific ECFCs. These data indicate that there are two distinguishable circulating ECFC types, blood and lymphatic, which are likely to have discrete functions during neovascularization. RNA was isolated from 2 blood-specific ECFC cell lines and 2 lymphatic-specific ECFC cell lines 3 separate times each

Project description:Human induced pluripotent stem (hiPS) cells and human embryonic stem (hES) cells differentiate into cells of the endothelial lineage, but derivation of cells with human umbilical cord blood endothelial colony forming cell (ECFC)-like properties has not been reported. Here we describe a novel serum- and stromal cell-free ECFC differentiation protocol for the derivation of clinically relevant numbers of ECFCs (> 108) from hiPS and hES cells. We identified NRP-1+CD31+ selected cells that displayed a stable endothelial phenotype exhibiting high clonal proliferative potential, extensive replicative capacity, formation of human vessels that inosculated with host vasculature upon transplantation, but lacking in teratoma formation in vivo. We also identified NRP-1-VEGF165-KDR-mediated activation of KDR as a critical mechanism for the emergence and derivation of ECFCs from hiPS and hES cells. This protocol advances the field by generating highly replicative but stable endothelial cells for use as a potential cell therapy for human clinical disorders.

Project description:Endothelial progenitor cells (EPCs) are circulating endothelial precursors shown to incorporate into foci of neovascularisation. Herein, we describe phenotypic characteristics of an EPC sub-type called endothelial colony-forming cells (ECFCs). Peripheral blood-isolated ECFCs expressed endothelial and progenitor surface antigens and displayed cobblestone-patterned colonies with clonal proliferative and angiogenic capacities in vitro. ECFCs demonstrated endothelial cell-like shear stress responses including cell alignment and PECAM-1 expression. Proteomic comparison with an endothelial reference population (human umbilical vein endothelial cells) confirmed a similar proteomic profile. Hierarchical clustering revealed two distinct ECFC clusters with differences in cell growth, proliferation and angiogenesis capacities. The cluster with compromised functionality was also associated with elevated blood pressure and impaired lipid profile. Our findings described an endothelial-like phenotype of blood-derived ECFCs with distinctive proteomic signatures based on cellular and clinical characteristics. ECFCs may aid in identifying novel mechanisms associated with cardiovascular disease risk and new targets to enhance angiogenesis.

Project description:Endothelial colony forming cells (ECFC) are circulating endothelial progenitors that are recruited to sustain endothelial function, vascular growth and repair. They are particularly abundant in the perinatal period and can be isolated from umbilical cord blood, thus representing neonatal ECFC. In this study, we profiled neonatal ECFC depending on maternal metabolic derangements to investigate intrauterine epigenetic programming.

Project description:Background Endothelial cells are crucial for hemostasis as they produce Von Willebrand factor (VWF). Von Willebrand Disease (VWD) results from a deficiency or defects in VWF, However, diagnosis is difficult due to large differences between gene variants and bleeding phenotype. Here, we analyze the endothelial compartment of patients with VWD using Endothelial Colony Forming Cells (ECFCs). Methods 13 healthy controls and 10 patients were included and a total of 29 ECFC clones were derived. Plasma was analyzed and ECFC gene expression was measured by qPCR which was used to characterize clones. ECFCs were then morphologically and functionally tested by ELISA, imaging, scratch assay and mass spectrometry. Results VWF plasma levels and activity was reduced in patients, although values were higher than historically measured. Through hierarchical clustering of RNA expression profiles, we classified ECFCs into 2 clusters. Patients were matched with controls from the same cluster. Patient ECFCs did not show a uniform phenotype, but 3 of the 5 patients that did not respond to DDAVP showed clear retention of VWF in the endoplasmic reticulum. Furthermore, MS data showed proteomic clustering overlapping with RNA profiles and revealed a third group from lymphatic origin. An inverse protein correlation was seen between VWF levels and WPB count and cell area. No clear patient phenotype was observed but unique proteins were downregulated per clone. Conclusion This study investigates a broad panel of ECFCs derived from both healthy and diseased donors through comprehensive characterization using functional assays and proteomics. It emphasizes the current opportunities and challenges of utilizing ECFCs as a model to study WPB-specific mechanisms, while also providing an extensive overview of the molecular regulation of WPB machinery across endothelial cells and its functional implications.

Project description:This is an investigation of whole genome gene expression level in human coronary endothelial cells (HCAEC) and human pulmonary endothelial cells (HPAEC) stimulated by FK565 or LipidA. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in and aortic root including aortic valves, slight in aorta and absent in other arteries. The in vitro production of proinflammatory chemokine/cytokine by FK565 is higher in HCAEC than in HPAEC, suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular cell itself. A six chip study using total RNA recovered from HCAEC and HPAEC which were stimulated by LipidA or FK565 in vitro. HCAEC and HPAEC were stimulated with FK565 (10µg/mL) or LipidA (100ng/mL) for 24 hours in 12-well plates (10,000 cells/cm2). Total RNA was extracted and subjected to RNA microarray analysis.

Project description:Hypoxia controls reparative angiogenesis. MiRNAs are master regulators of gene expression in hypoxia and angiogenesis. However, we do not yet have a clear understanding of how hypoxia-induced miRNAs modulate vasoreparative processes. Here, we identify miR-130a as a mediator of the hypoxic response in human primary endothelial colony forming cells (ECFCs), a well-characterized subtype of endothelial progenitor. Under hypoxic conditions, miR-130a overexpression enhances ECFC pro-angiogenic capacity in vitro and potentiates their vasoreparative properties in vivo. Mechanistically, miR-130a orchestrates upregulation of VEGFR2, activation of STAT3-dependent transcription, and accumulation of HIF1α via translational inhibition of DDX6. These findings unveil a new role for miR-130a in hypoxia, whereby it modulates the VEGFR2/STAT3/HIF1α axis to increase the vasoregenerative capacity of ECFCs.
