Pathophysiology of Tumor Neovascularization
Neovascularization is essential to the process of development and differentiation of tissues in the vertebrate embryo, and is also involved in a wide variety of physiological and pathological conditions in adults, including wound repair, metabolic diseases, inflammation, cardiovascular disorders, and tumor progression. Thanks to cumulative studies on vasculature, new therapeutic approaches have...
متن کاملExploring Means of Exploiting Tumor Pathophysiology
Cancer is a devastating disease. A silent stalker, its precursors lurk in the air we breathe, the food we eat, and paradoxically, in the very cellular instructions essential to reproducing and sustaining life. As the leading cause of death in persons under 85 years of age, cancer is associated with one out of every four deaths in the United States.1 In 2006, Americans can expect 1,399,790 new c...
متن کاملTumor Dormancy in Vivo by Prevention of Neovascularization
Dormant solid tumors were produced in vivo by prevention of neovascularization. When small fragments of anaplastic Brown-Pearce carcinoma were implanted directly on the iris in susceptible rabbits, they always vascularized. A characteristic growth pattern, consisting of prevascular, vascular, and late phases, was observed, which terminated with destruction of the eye within 2 wk. The beginning ...
متن کاملProlonged tumor dormancy by prevention of neovascularization in the vitreous.
Tumors release a diffusible substance that stimulates neovascularization. To study the neovascularization that occurs in diabetic retinopathy, we implanted V2 carcinomas and mouse ependymoblastomas into the vitreous of experimental animals. In the vitreous, unlike previous sites, the tumors failed to stimulate neovascularization. They grew for weeks as small, unvascularized, three-dimensional a...
متن کاملRegulation of Tumor Angiogenesis and Choroidal Neovascularization by Endogenous Angioinhibitors.
Angiogenesis is the process of neovascularization from parent blood vessels, which is a prerequisite for many physiological and pathological conditions and is regulated by a balance between endogenous angioinhibitors and angioactivators or angiogenic factors. Imbalance between angioinhibitors and angioactivators is associated with neovascularization capacity during progression of tumor developm...
