Endothelial progenitor cells (EPC) enhance endothelial cell repair, improve endothelial dysfunction and are a predictor for cardiovascular mortality. High-density lipoprotein (HDL) cholesterol levels inversely correlate with cardiovascular events and have vasculoprotective effects. Here we postulate that HDL influences EPC biology. HDL and EPC were isolated according to standard procedures. Dif...

AIMS To study the effect of endothelial progenitor cell (EPC) treatment on intracerebral hemorrhage (ICH) in rats and elucidate possible mechanisms. METHODS The rats were randomly divided into three groups: (1) EPC group: ICH + EPC, (2) phosphate-buffered saline group: ICH + PBS, and (3) sham group. EPCs were transplanted intravenously 6 h after ICH. Modified neurological severity score was u...

AIMS The aim of the study was to determine the influence of endothelial progenitor cells (EPC) on erectile dysfunction (ED). EPC play a major role in repair mechanisms of the endothelial monolayer, but the role of EPC in ED is unclear. METHODS AND RESULTS Circulating levels of CD34(+)/KDR(+) and CD133(+) EPC were determined in 119 patients with known coronary artery disease. ED was evaluated ...

Late outgrowth endothelial progenitor cells (LO-EPC) possess a high proliferative potential, differentiate into vascular endothelial cells (EC), and form networks, suggesting they play a role in vascular repair. However, due to their scarcity in the circulation there is a requirement for ex vivo expansion before they could provide a practical cell therapy and it is currently unclear if they wou...

Increased numbers of submucosal vessels are a consistent pathologic component of asthmatic airway remodeling. However, the relationship between new vessel formation and asthmatic inflammatory response is unknown. We hypothesized that angiogenesis is a primary event during the initiation of airway inflammation and is linked to the recruitment of bone marrow-derived endothelial progenitor cells (...

EPC projects are promising all over the world, though the management of EPC projects at present did not seem scientific and systematized particularly in the developing countries. As EPC projects are diversified in knowledge which covers different professional fields, lifecycle periods and stakeholders, the knowledge integration not only helps solve the problems of management inside the current ...

Recessive mutations of the early phase change (epc) gene in maize affect several aspects of plant development. These mutations were identified initially because of their striking effect on vegetative phase change. In certain genetic backgrounds, epc mutations reduce the duration of the juvenile vegetative phase of development and cause early flowering, but they have little or no effect on the n...

This paper addresses the Hardware Trojan issues in passive EPC C1G2 RFID Tags. We propose in this paper to study the insertion of malicious circuit in EPC GEN2 RFID tags. The description and the implementation of several different Hardware Trojans are first discussed. Then they are all evaluated in an EPC GEN2 environment using a dedicated FPGA based tag emulator. The evaluation focuses on crit...

We report two cases of eccrine porocarcinoma (EPC), one of intrepidermal EPC (IEEPC) and one of intradermal invasive EPC (IDEPC) in an immunohistochemical study of cytokeratins (CK) using nine different anti-keratin antibodies against CK1, 7, 8, 10, 14, 16, 17, 18 and 19. IEEPC expressed terminal differentiated CK1 and CK10. In contrast, IDEPC expressed simple-epithelial keratins such as CK7, 8...

Circulating endothelial progenitor cells (EPC) contribute to postnatal neovascularization. We identified the cytochrome P450 4A/F-20-hydroxyeicosatetraenoic acid (CYP4A/F-20-HETE) system as a novel regulator of EPC functions associated with angiogenesis in vitro. Here, we explored cellular mechanisms by which 20-HETE regulates EPC angiogenic functions and assessed its contribution to EPC-mediat...
