BACKGROUND Vascular endothelial growth factor-B (VEGF-B) binds to VEGF receptor-1 and neuropilin-1 and is abundantly expressed in the heart, skeletal muscle, and brown fat. The biological function of VEGF-B is incompletely understood. METHODS AND RESULTS Unlike placenta growth factor, which binds to the same receptors, adeno-associated viral delivery of(More)
Therapeutic angiogenesis provides a potential alternative for the treatment of cardiovascular ischemic diseases. Vascular endothelial growth factor (VEGF) is an important component of the angiogenic response to ischemia. Here we used adeno-associated virus (AAV) gene delivery to skeletal muscle to examine the effects of VEGF vs. a stabilized form of(More)
BACKGROUND For clinically relevant proangiogenic therapy, it would be essential that the growth of the whole vascular tree is promoted. Vascular endothelial growth factor (VEGF) is well known to induce angiogenesis, but its capability to promote growth of larger vessels is controversial. We hypothesized that blood flow remodels vascular growth during VEGF(More)
Vessel stabilization and the inhibition of side effects such as tissue edema are essential in angiogenic gene therapy. Thus, combination gene transfers stimulating both endothelial cell and pericyte proliferation have become of interest. However, there is currently little data to support combination gene transfer in large animal models. In this study, we(More)
Angiogenic therapy, which involves the use of an exogenous stimulus to promote blood vessel growth, is an attractive approach for the treatment of ischemic diseases. It has been shown in animal models that the stimulation of blood vessel growth leads to the growth of the whole vascular tree, improvement of ischemic tissue perfusion and improved muscle(More)
AIMS We investigated the effects of angiogenic gene therapy with adenoviral placental growth factor(131) (AdPlGF) on aerobic capacity and exercise tolerance in a rabbit hindlimb ischaemia model. We also assessed whether strong angiogenic changes such as capillary arterialization and formation of artery-venous shunts compromise oxygen transport to target(More)
A ngiogenesis, the process of the formation of new blood vessels from preexisting ones, occurs in all vascularized organs during embryogenesis. In adults, angiogenesis is observed mainly in a variety of pathological conditions such as wound healing, tumor growth, and proliferative retinal vasculopathies. Members of the vascular endothelial growth factor(More)
