Transplantation of endothelial progenitor cells (EPCs) restores endothelial function. The present study was designed to determine the effect of autologous EPCs transplantation on the regeneration of endothelium in mice. Mice splenectomy was performed 14 days before carotid artery injury, and mononuclear cells were isolated and cultured in endothelial growth(More)
BACKGROUND Although age-related impairment of endothelial progenitor cells (EPCs) has been documented in recent studies, the detailed role of aging-induced environment in EPCs remains unclear. METHODS Two and 20 months old Sprague-Dawley female rats were used in the present study. EPCs isolated from young (YEPCs) and aged (AEPCs) rats were cultured with(More)
BACKGROUND Endothelial progenitor cells (EPCs) can be mobilized by cytokines and recruited to sites of neovascularization and neointima, where they differentiate into mature endothelial cells. It is thought that stromal cell-derived factor-1alpha (SDF-1alpha) is involved in ischemia-mediated mobilization and homing of EPCs and in vascular injury-mediated(More)
A mouse model of endothelial denudation in the common carotid artery is usually established with a flexible wire under a dissecting microscope. In this article, we introduce a modified procedure to establish a carotid arterial injury mouse model in which no dissecting microscope is used. In the nonmicrosurgical procedure, carotid clamps, which were used to(More)
Endothelial progenitor cells (EPCs), a CXCR4-bearing cell line, are thought to positively influence reendothelialization, vascular repair, and angiogenesis. AMD3100, a highly selective antagonist of stromal cell derived factor (SDF)-1 that binds to its receptor, CXCR4, has been shown to induce rapid mobilization of hematopoietic stem cells in mice, dogs,(More)
Estrogen induces endothelial progenitor cells (EPCs) migration and proliferation, which may serve as a potential target for coronary artery disease, but the mechanisms are unclear. We hypothesized that estrogen receptors (ERs) and phosphatidylinositol 3-kinase (PI3K) signaling pathway, which represent particularly important roles of action for estrogen, may(More)
Endothelial progenitor cells (EPCs) play an important role in vascular repair. We hypothesized that overexpression of endothelial nitric oxide synthase (eNOS) in EPCs enhances inhibition of neointimal hyperplasia and restores endothelium-dependent vasodilatation in injured vessels. Bone marrow-derived EPCs were cultured and expanded in endothelial basal(More)
OBJECTIVE To observe the effect of platelet derived growth factor receptor β (PDGFR-β) transfected endothelial progenitor cells (EPCs) on vascular regeneration. METHODS Spleen-derived mononuclear cells (MNCs) were isolated using density gradient centrifugation and induced with special culture medium. EPCs transfection was performed with Lipofectamine(TM)(More)
Transplantation of endothelial progenitor cells (EPCs) restores endothelial function in patients with endothelial dysfunction and initial denudation. The goal of the present study was to determine the effect of cryopreserved human umbilical cord blood (UCB)-derived EPC infusion on the repair of carotid artery injury in nude rats. Mononuclear cells (MNCs)(More)
The proliferation, migration, and angiogenesis of endothelial progenitor cells (EPCs) play critical roles in postnatal neovascularization and re-endothelialization following vascular injury. Here we evaluated whether the over-expression of platelet-derived growth factor receptor-β (PDGFR-β) can enhance the PDGF-BB-stimulated biological functions of EPCs(More)
