The polyol pathway consists of two enzymes aldose reductase (AR) and sorbitol dehydrogenase (SDH); the former is the first enzyme in the polyol pathway, that catalyzes the reduction of glucose to sorbitol, the latter is the second one, that converts sorbitol to fructose using by NAD + as a cofactor. We along with others have recently found that SDH activity, the second step in the polyol pathway,...
The first vascular structures in embryos are formed by vasculogensis, the de novo formation of blood vessels from angioblasts. However, angiogenesis, the sprouting of capillaries from pre-existing blood vessels, are also involved in the development of embryonic vascular system in certain organs, such as the kidney or the brain. These facts led us to speculate that embryonic tissues could produce potent...
