The Regulation of Blood Vessel Growth
The vascular system forms through a combination of vasculogenesis and angiogenesis. In vasculogenesis, vessels form de novo via the assembly of endotheial precursors called angioblasts, whereas in angiogenesis new vessels arise by migration and proliferation of endothelial cells from preexisting vessels. Although the two processes are distinct in some respects, recent evidence suggests that the...
متن کاملDynamic mechanisms of blood vessel growth.
The formation of a polygonal configuration of proto-blood-vessels from initially dispersed cells is the first step in the development of the circulatory system in vertebrates. This initial vascular network later expands to form new blood vessels, primarily via a sprouting mechanism. We review a range of recent results obtained with a Monte Carlo model of chemotactically migrating cells which ca...
متن کاملDynamic responses in retinal vessel caliber with flicker light stimulation in eyes with diabetic retinopathy.
PURPOSE This study investigated the responses of retinal vessels to flickering light in diabetic patients with various stages of diabetic retinopathy (DR). METHODS This cross-sectional observational study evaluated adult subjects with diabetes mellitus. The Dynamic Vessel Analyzer (DVA) was used to measure retinal vascular dilatation in response to diffuse illuminance flicker. Diabetic retino...
متن کاملRegulation of blood vessel versus lymphatic vessel growth in the cornea.
PURPOSE In the present study, the authors developed novel models to stimulate blood vessel formation (hemangiogenesis) versus lymphatic vessel formation (lymphangiogenesis) in the cornea. METHODS Micropellets loaded with high-dose (80 ng) or low-dose (12.5 ng) basic fibroblast growth factor (bFGF) were placed in BALB/c corneas. Angiogenic responses were analyzed by immunohistochemistry to qua...
متن کاملAltair: Automatic Image Analyzer to Assess Retinal Vessel Caliber
The scope of this work is to develop a technological platform specialized in assessing retinal vessel caliber and describing the relationship of the results obtained to cardiovascular risk. Population studies conducted have found retinal vessel caliber to be related to the risk of hypertension, left ventricular hypertrophy, metabolic syndrome, stroke, and coronary artery disease. The vascular s...
