BACKGROUND: There is increasing evidence implying that the early and functionally highly active circulating endothelial progenitor cell (CEPC) phenotype (CD34-/CD133+/KDR+) with osteogenic potential (OCN+) might link between vascular atherosclerotic calcification and mechanisms of bone metabolism. We sought to evaluate the early OCN+ CEPC counts as an independent biomarker for the severity of coronary artery disease (CAD). METHODS: Peripheral blood samples were drawn from 593 patients undergoing clinically indicated coronary angiography...

: : Bone marrow-derived progenitor cells are mobilized into the peripheral blood after acute myocardial injury and in chronic ischemic heart disease. However, the mechanisms responsible for this mobilization are poorly understood. We examined the relationship between plasma levels of bioactive lipids and number of circulating progenitor cells (CPCs) in patients (N = 437) undergoing elective or emergent cardiac catheterization. Plasma levels of sphingosine-1 phosphate (S1P) and ceramide-1 phosphate (C1P) were quantified using mass spectrometry...

OBJECTIVE: Vascular restenosis remains a major obstacle to long-term success after vascular intervention. Circulating progenitor cells have been implicated in restenosis, and yet it has remained unclear if these cells, particularly nonendothelial progenitors, have an active role in this pathologic process. We hypothesized that circulating CD34(+)/c-kit(+) progenitors would increase after vascular injury, mirrored by changes in the injury signal, stromal cell-derived factor 1α (sdf1α)...

BACKGROUND AND AIMS: Ischemia stimulates a reparative response resulting in mobilization of circulating progenitor cells (CPCs). We hypothesized that women with chronic myocardial ischemia from coronary microvascular disease (CMD) will mobilize CPCs. METHODS: In 123 women with ischemic symptoms and signs but no obstructive coronary artery disease (CAD) enrolled in the Women's Ischemia Syndrome Evaluation - Coronary Vascular Dysfunction Study (WISE-CVD), we measured coronary flow reserve (CFR) in response to intracoronary adenosine...

OBJECTIVES: Circulating endothelial progenitor cells (EPCs), which have the ability to differentiate into mature endothelial cells, can elicit angiogenesis, vasculogenesis and vessel repair in cardiac ischemia and vascular injuries caused by endothelial damage. Serum 1,5-anhydro-d-glucitol (1,5-AG), which is a useful clinical marker of postprandial hyperglycemia, eicosapentaenoic acid (EPA), and arachidonic acid (AA) are newly identified risk factors for coronary artery disease (CAD)...

RATIONALE: Peripheral arterial disease (PAD) is a clinical manifestation of extracoronary atherosclerosis. Despite sharing the same risk factors, only 20% to 30% of patients with coronary artery disease (CAD) develop PAD. Decline in the number of bone marrow-derived circulating progenitor cells (PCs) is thought to contribute to the pathogenesis of atherosclerosis. Whether specific changes in PCs differentiate patients with both PAD and CAD from those with CAD alone is unknown. OBJECTIVE: Determine whether differences exist in PCs counts of CAD patients with and without known PAD...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is involved in cholesterol homeostasis, inflammation, and oxidative stress. This study investigated the association of plasma PCSK9 levels with the presence and severity of peripheral artery disease (PAD) and with parameters of endothelial homeostasis. METHODS AND RESULTS: A post hoc analysis of 2 randomized trials (115 patients, 44 with PAD and 71 without atherosclerotic disease) was conducted. Patients with PAD had significantly higher plasma PCSK9 levels than those without (471...

The role of endothelial progenitor cells (EPCs) in peripheral artery disease (PAD) remains unclear. We hypothesized that EPC mobilization and function play a central role in the development of endothelial dysfunction and directly influence the degree of atherosclerotic burden in peripheral artery vessels. The number of circulating EPCs, defined as CD34(+)/KDR(+) cells, were assessed by flow cytometry in 91 subjects classified according to a predefined sample size of 31 non-diabetic PAD patients, 30 diabetic PAD patients, and 30 healthy volunteers...

The clinical implications of early and late endothelial progenitor cells (EPCs) in coronary artery disease (CAD) remain unclear. We investigated endothelial dysfunction in CAD by simultaneously examining early and late EPC colony formation and gene expression of specific surface markers in EPCs. EPCs were extracted from a total of 83 subjects with (n = 47) and without (n = 36) CAD. Early and late EPC colonies were formed from mononuclear cells extracted from peripheral blood. We found that fewer early EPC colonies were produced in the CAD group (7...

The extent and clinical significance of stem and progenitor cell (SPC) increases in response to lower-extremity ischemia in people with peripheral artery disease (PAD) are unclear. We compared changes in SPC levels immediately following a treadmill exercise test between individuals with and without PAD. Among participants with PAD, we determined whether more severe PAD was associated with greater increases in SPCs following treadmill exercise-induced lower-extremity ischemia. We measured SPC levels in 25 participants with PAD and 20 without PAD before and immediately after a treadmill exercise test...

BACKGROUND: Endothelial dysfunction is central to the pathogenesis of coronary artery disease, but the role of local and circulating endothelial progenitor cells in maintaining vascular health is poorly understood. We hypothesised that impaired local and circulating vascular repair mechanisms predispose to endothelial dysfunction and the premature onset of coronary artery disease. METHODS AND RESULTS: Patients with premature coronary artery disease (n = 16) and healthy age- and sex-matched controls (n = 16) underwent venous occlusion plethysmography with intra-arterial infusion of acetylcholine and sodium nitroprusside...

BACKGROUND AND AIMS: Suboptimal vitamin D status was recently acknowledged as an independent predictor of cardiovascular diseases and all-cause mortality in several clinical settings, and its serum levels are commonly reduced in Rheumatoid Arthritis (RA). Patients affected by RA present accelerated atherosclerosis and increased cardiovascular morbidity and mortality with respect to the general population. In RA, it has been reported an impairment of the number and the activity of circulating proangiogenic haematopoietic cells (PHCs), including CD34+, that may play a role in endothelial homeostasis...

Poor vascular homeostasis drives many clinical disorders including diabetes, arthritis, atherosclerosis, and peripheral artery disease. Local tissue ischemia resultant of insufficient blood flow is a potent stimulus for recruitment of endothelial progenitor cells (EPCs). This mobilization and homing is a multi-step process involving EPC detachment from their steady state bone marrow niches, entry into circulation, rolling along vessel endothelium, transmigration, and adhesion to denuded extracellular matrix (ECM) where they may participate in neovessel formation...

BACKGROUND AND PURPOSE: We evaluated the hypothesis that the number of circulating EPC could be associated with the risk of stroke recurrence (SR) or vascular events (VE) after an ischemic stroke. METHODS: We studied prospectively consecutive patients with cerebral infarction within the first 48 hours after the onset. We recorded demographic factors, vascular risk factors, previous Rankin scale (RS) score, and etiology. We analyzed EPC counts by flow cytometry in blood collected at day 7 and defined EPC as CD34+/CD133+/KDR+ cells...

Heart failure is one of the most prominent causes of morbidity and mortality worldwide. According to the World Health Organization, coronary artery disease and myocardial infarction (MI) are responsible for 29% of deaths worldwide. MI results in obstruction of the blood supply to the heart and scar formation, and causes substantial death of cardiomyocytes in the infarct zone followed by an inflammatory response. Current treatment methodologies of MI and heart failure include organ transplantation, coronary artery bypass grafting, ventricular remodeling, cardiomyoplasty, and cellular therapy...

Critical limb ischaemia is the most severe clinical manifestation of peripheral arterial disease. The circulating endothelial progenitor cells (EPCs) play important roles in angiogenesis and ischemic tissue repair. The increase of circulating EPC numbers by using mobilization agents is critical for obtaining a better therapeutic outcome in patients with ischemic disease. Here, we firstly report a novel small molecule, Me6TREN (Me6), can efficiently mobilize EPCs into the blood circulation. Single injection of Me6 induced a long-lasting increase in circulating Flk-1(+) Sca-1(+) EPC numbers...

Endothelial progenitor cells (EPCs) are associated with vascular repairing and progression of atherosclerotic lesion. It may lead to coronary artery disease (CAD) if circulating EPCs lose their function. Continuous nitroglycerin (NTG) therapy causes increased vascular oxidative stress and endothelial dysfunction. The aim of this study was to investigate the effects of NTG on the proliferation of human peripheral blood-derived EPCs. EPC cultures, collected from 60 CAD patients and cultured for 7-12 days, were treated with different concentrations of NTG (0...

Restenosis is the pathophysiological process occurring in 10-15% of patients submitted to revascularization procedures of coronary, carotid and peripheral arteries. It can be considered as an excessive healing reaction of the vascular wall subjected to arterial/venous bypass graft interposition, endarterectomy or angioplasty. The advent of bare metal stents, drug-eluting stents and of the more recent drug-eluting balloons, have significantly reduced, but not eliminated, the incidence of restenosis, which remains a clinically relevant problem...
