36 results about "Endothelial Precursor Cell" patented technology

Initially in embryonic vasculature development, endothelial precursor cells form a common progenitor vessel which then gives rise to the first artery (dorsal aorta) and vein (cardinal vein) by selective sprouting and subsequent arterial-venous cell segregation4 (see also Chapter 1).

Means and methods for the recruitment and identification of stem cells

InactiveUS20060210532A1Inhibit recruitmentIncreased engraftmentBiocideHydroxy compound active ingredientsProgenitorHematopoietic cell
Described are methods of modulating stem / progenitor cell recruitment involving molecules that agonize the formation of plasmin stimulating the recruitment of stem / progenitor cells, including hematopoietic and endothelial precursor cells. Conversely, antagonists of plasmin can inhibit recruitment of the stem cells. In addition, the identification of the uPA receptor (uPAR) as a retention signal for stem cells in their niche suggests a novel method for increased engraftment and isolation of multipotent stem cells.

Mammalian endothelial cell model systems

AC133+ / CD34+ cells isolated from human bone marrow can be stimulated with the pro-angiogenic factors VEGF, bFGF, and heparin, resulting in the generation of a population of cells that is adherent and possesses many of the same properties as mature endothelial cell types, HMVECs and HUVECs. The newly-formed, endothelial-like cells are referred as adherent endothelial precursor cells (aEPCs); these cells appear to be intermediates between haematopoietic stem cells (HSCs) and mature endothelial cells. Direct comparison of aEPCs with HMVECs and HUVECs in several in vitro functional assays, such as tube formation, migration, invasion, and expression of cells surface markers, reveals differences and similarities. In a Matrigel™ matrix angiogenesis assay the aEPCs form vessels in vivo and interact with human ovarian cancer cells. Mouse cell lines that are useful models for tumor endothelial cells are identified by determining mRNA and protein expression levels of murine homologs of tumor endothelial markers. Mouse cell lines selected as models for tumor endothelial cells can be used to evaluate pro-angiogenic and anti-angiogenic factors.
