Project description:Derivation and expansion of human umbilical cord blood-derived endothelial colony forming cells under serum-free conditions - a transcriptome analysis. Endothelial colony forming cells (ECFCs) were isolated from term umbilical cord blood units. ECFCs were expanded under standard, fetal bovine serum (FBS) containing endothelial medium, or transferred to chemically defined endothelial media without FBS. Microarray expression profiling was applied to compare the transcriptome profiles in FBS-containing versus FBS-free culture.

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. Transcriptome sequencing of undifferentiated day 0 hiPS cells, Day 3 differentiated hiPS-derived mesoderm proginator cells, Day 12 hiPS-derived NRP-1+CD31+ cells, Day 12 H9-hES-derived NRP-1+CD31+ cells and cord blood-derived Endothelial colony forming cells.

Project description:miRNA profiling was carried out using the miRCURY LNA™ microRNA Array (5th gen - hsa, mmu & rno). microRNA profiling of CB and PB-derived ECFCs from 3 independent donors from each cell source. To identify and understand the regulation of endothelial cell functions through comparing miRNA expression profiling of cord blood (CB) derived endothelial colony forming cells (ECFCs) and peripheral blood (PB) ECFCs

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:Endothelial colony-forming cells (ECFCs) have been reported as promising cells for regenerative medicine thanks to their angiorepair properties. Transcription factors are primary determinants of the functional capacity of the cells and TAL1 has been shown as a critical regulator of endothelial lineage in both development and adult life. However, only few (three) TAL1 targets have been identified so far in mouse and human endothelial cells. This ChIP-seq experiment was designed to identify genome binding/occupancy of TAL1 by ChIP and high throughput sequencing in primary human endothelial stem/progenitor cells. TAL1 ChIP and IgG ChIP (negative control) were performed in crosslinked ECFCs derived from human umbilical cord blood.

Project description:Mesenchymal stem/stromal cells (MSCs) are multipotent cells that can differentiate into a variety of cell types forming connective tissue and skeleton, and are essential participants in the development of all organs. However, MSC precursors remain largely unknown. In human embryonic stem cells (hESCs) directed to mesendodermal differentiation through coculture with OP9 stromal cells, we identified a population of mesodermal cells by surface expression of apelin receptor (APLNR1). APLNR+ cells were enriched with precursors generating compact spheroid colonies in semisolid suspension culture. Being formed by single cells, these colonies consisted of a uniform population of mesenchymal cells with a transcriptional profile representative of embryonic mesenchyme originating from lateral plate/extraembryonic mesoderm. Mesenchymal colony formation required serum-free medium and FGF2 as a colony-forming factor, could be significantly enhanced by PDGF-BB, but suppressed by VEGF. When transferred to the adherent cultures in serum-free medium with FGF2, individual colonies gave rise to multipotential mesenchymal cell lines with typical phenotype (CD146+CD105+CD73+CD31-CD43-CD45-), differentiation (chondro-, osteo-, and adipogenesis) and proliferation (>80 doublings) potentials. Consistent with lineage-restricted differentiation pattern, neither endothelial nor hematopoietic cells could be produced from adherent mesenchymal cultures, however endothelial cells could be derived from mesenchymal colonies in the early days of colony-forming culture suggesting that mesenchymal cells arose from cells with primary angiogenic potential (mesangioblasts). Together these studies identified mesangioblasts as the earliest clonogenic mesenchymal precursors at this stage of their specification from mesoderm. This set (11 samples) of expression data is sequential stages of MSC development from hESCs (H1), namely ALPNR+ mesodermal precursors isolated on day 2 and day 3 differentiation, mesangioblast (MB) cores (Day 2 H1-derived cores), hemangioblast (HB) cores (day 3 H1-derived cores), mesangioblast (MB) and hemangioblast (HB) colonies, and colony-derived MSC lines at passage 1 and 5.
