آمیزه مناسبی از اکتینیدین میوه کیوی و تریپسین برای جداسازی و کشت سلولهای اندوتلیال آئورت موش صحرایی
Background: Proteolytic enzymes, especially collagenases, are used for digestion of extracellular matrix, cell isolation and primary culture. Because of the problems in purification and low amount of collagenases in bacterial or animal sources, it is important to find new sources of the enzymes. So, in the present study actinidin, a plentiful protein in kiwifruit was purified and a mixture of ...
introduction: endothelial progenitor colony forming unit-endothelial cells (cfu-ec) were first believed to be the progenitors of endothelial cells, named endothelial progenitor cells. further studies revealed that they are monocytes regulating vasculogenesis. the main hindrance of these cells for therapeutic purposes is their low frequency and limited replicative potentials. this study was unde...
Background & Aims : Aging and the loss of endogenous estrogen production after menopause are accompanied by increases in blood pressure and endothelial dysfunction. Exercise training improves endothelial function in patients with hypertension. The aim of this study was to examine the effect of aerobic training on some markers of endothelial function in hypertensive postmenopausal women. M...
Background: Human embryonic stem cells (hESCs) are capable of self-renewal and large-scale expansion. They also have the capacity to differentiate into a variety of cell types including liver, cardiac and neuron cells. However, it is not yet clear whether hESCs can differentiate to hemangioblasts under in-vitro conditions. Hemangioblasts are bipotential progenitors that can generate hematopoiet...
background: vascular endothelial growth factor (vegf) is a coordinate regulator of physiological angiogenesis during embryogenesis, skeletal growth and reproductive functions. there are several types of vegf, including vegf165. vegfs stimulate endothelial cell growth, angiogenesis, and capillary permeability. low induction temperature is a major factor for expression of the recombinant vegf165 ...
development of phytotherapies aimed at angiogenesis inhibition, in combination with classical anti-cancer therapies, is among the most intensively studied approaches for treatment of cancer. epidemiological and animal studies have indicated that consumption of allium species like shallot is associated with a reduced risk of cancer development. as a continuation of our efforts to study and chara...
A microfluidic assay integrated with capillary network-inspired microcapillary arrays and endothelial-associated protein functionalization enables concurrent assessment of red blood cell adhesion occlusion.
purpose: to report the confocal microscopic features of endothelial vacuolation in donated corneas and to confirm the observed changes by transmission electron microscopy. methods: confocal and transmission electron microscopy were performed on donated corneas with endothelial vacuole formation on slitlamp biomicroscopy. the ultrastructural findings were also compared with those of a normal-loo...
Angiogenesis is the generation of new blood vessels from the existing vasculature. The angiogenic programme requires the degradation of the basement membrane, endothelial cell migration and invasion of the extracellular matrix, with endothelial cell proliferation and capillary lumen formation before maturation and stabilization of the new vasculature. Angiogenesis is dependent on a delicate equ...
Objective: The purpose was to confirm the significance of Anti-endothelial cell antibodies(AECA) in chronic obstructive pulmonary disease (COPD) and validate effect methylprednisolone intervention.
