Vascular endothelial growth factor receptor 2 (VEGFR2) transmits signals of crucial importance to vasculogenesis, including proliferation, migration, and differentiation of vascular progenitor cells. Embryonic stem cell-derived VEGFR2(+) mesodermal cells differentiate into mural lineage in the presence of platelet derived growth factor (PDGF)-BB or serum but into endothelial lineage in response...

UNLABELLED The discovery of circulating endothelial progenitor cells (EPCs) opened up a new era of EPC-based therapies for cardiovascular diseases. While researchers are enthusiastic about applying EPCs to clinical therapy, progress has been substantially limited due to the lack of a thorough characterization and understanding of early and late outgrowth EPCs (also called endothelial colony-for...

objective: cardiac cell differentiation with the help of mirnas has recently opened a promising window for the restoration of myocardial infarction. independent mir-1-2/133a-1 and mir-206/133b clusters are known to be expressed in cardiac and skeletal muscles, respectively. mir-133b differs from mir-133a by only one nucleotide. the sequence similarity of these two mirnas suggests that they targ...

Origin to Blood Vessel Formation To the Editor: Crosby et al1 noted in their report that the recruitment of bone marrow–derived endothelial progenitor cells to newly forming blood vessels might have been hitherto overlooked. Postulated already a century ago,2 there is now ample evidence for a close association between blood progenitor cells and angiogenesis3 and the existence of a hemangioblast...

AIMS Recent results generated in a mouse model suggest that tumour angiogenesis/vasculogenesis can be initiated and maintained by bone marrow derived endothelial progenitor cells. This present study investigated the distribution and frequency of CD133 positive endothelial progenitor cells in patients with non-small cell lung cancer (NSCLC) (tumour tissue and tumour free lung regions) and health...

OBJECTIVE We quantified endothelial progenitor cell (EPC) engraftment into the endothelial layer as an index of progenitor-mediated endothelial repair. Studies were conducted in C57BL/6J and in apolipoprotein E-deficient (apoE(-/-)) mice. We also investigated the possibility that high-density lipoproteins (HDL) may promote progenitor-mediated endothelial repair. METHODS AND RESULTS Thoracic a...

BACKGROUND AND OBJECTIVES The presence of circulating hematopoietic progenitor cells in patients with myeloproliferative diseases (MPD) has been described. However, the exact nature of such progenitor cells has not been specified until now. The aim of this work was to investigate the presence of endothelial precursor cells in the blood of patients with MPD and to assess the role of the endothel...

BACKGROUND Plasma high-density lipoprotein (HDL) levels have an inverse correlation with incidence of ischemic heart disease as well as other atherosclerosis-related ischemic conditions. However, the molecular mechanism by which HDL prevents ischemic disease is not fully understood. Here, we investigated the effect of HDL on differentiation of endothelial progenitor cells and angiogenesis in mu...
