چکیده انگلیسی
The factors controlling recruitment of endogenous and transplanted endothelial progenitor cells (EPC) to areas of neovascularization are largely unknown. In this study, we have examined the possibility that EPC migration and adhesion could be regulated by angiopoietin-2 (Ang2), a soluble ligand expressed by endothelial cells at sites of vessel remodelling and angiogenesis. We show for the first time that Ang2 causes a marked stimulation of EPC migration. This was specific for EPC as the ligand failed to affect endothelial cell migration. Ang2-stimulated EPC migration was inhibited by soluble Tie2 ectodomain. Furthermore, the ligand stimulated adhesion between EPC and endothelial monolayers.
