background: we investigated coronary angiogenesis and serum vascular endothelial growth factor (vegf) and its soluble receptor-1 (sflt-1) concentrations in two-kidney one-clip (2k1c) hypertensive rats before and after reversal of hypertension. methods: the animal groups were: (i) sham-clipped for 12 weeks; (ii) 2k1c for 12 weeks; (iii) sham-clipped for 12 weeks and unclipped for 12 weeks; and (...

we report a case of choroidal neovascularization (cnv) secondary to methylenetetrahydrofolate reductase (mthfr) gene mutation in a 20-year-old male patient with hypopituitarism. treatment with three consecutive injections of intravitreal ranibizumab (anti-vascular endothelial growth factor) resulted in significant improvement of the patient’s vision and the appearance of the macula. a search ...

Background: Vascular endothelial growth factor-A (VEGF-A), an endothelial cell-specific mitogen produced by various cell types, plays important roles in cell differentiation and proliferation. In this study we investigated the effect of recombinant VEGF-A on differentiation of mesenchymal stem cells (MSCs) to endothelial cells (ECs). Methods: VEGF-A was expressed in E. coli BL21 (DE3) and BL21...

Background: Several studies have shown that leukemia inhibitory factor (LIF) is one of the most important cytokinesparticipating in the process of embryo implantation and pregnancy, while, the role of this factor on vascular endothelialfactor-A (VEGF-A), as one of the most important angiogenic factor, has not been fully investigated yet. The aimof this study was to evaluate th...

background: henoch-schönlein purpura (hsp) is an lga mediated small vessel systemic vasculitis disease in children. the etiology and pathogenesis of hsp disease remain unknown. however, environmental and genetic risk factors could play important roles in susceptibility to hsp disease. in this study we investigated the association of 5՛-untranslated region polymorphism (-634g/c) of vegf gene wit...

background angiogenesis is an important biological process involved in the proliferation of endothelial cells, tumor growth and metastasis. vascular endothelial growth factor (vegf) is considered as a prominent regulator of angiogenesis which exerts the aforementioned effect(s) through its respective receptors (vegfr1 and vegfr2). vegf receptors are targeted as a therapeutic candidate for cance...

Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...

Vascular endothelial growth factor (VEGF) is a multifunctional cytokine with distinct functions in angiogenesis, lymphangiogenesis, vascular permeability, and hematopoiesis. VEGF is a highly conserved, disulfide-bonded dimeric glycoprotein of 34 to 45 kDa produced by several cell types including fibroblasts, neutrophils, endothelial cells, and peripheral blood mononuclear cells, particularly T ...

Trophoblast stem cells develop from polar trophoectoderm and give rise to the cells that generate the placenta. Trophoblast cells are responsible for the uterinal invasion and vascular remodeling during the implantation of the embryo. However this knowledge is not yet to be confirmed for trophoblast progenitor cells (TPCs). In this study, we aimed to demonstrate that human TPCs (hTPCs) express ...
