Gangrene, revascularization, and limb function improved with E-selectin/adeno-associated virus gene therapy

Abstract

Clinical Relevance: In the United States, >150,000 limb amputations are performed annually for critical limb ischemia (CLI) despite the use of medical and surgical therapy. Thus, novel therapeutic angiogenic concepts for CLI are still needed for limb salvage. We used a novel gene therapy approach in a mouse model of gangrene, the most severe form of CLI, to demonstrate the efficacy of our gene therapy with E-selectin. Preclinical studies such as ours are a vital step in the development of new therapies for CLI patients with threatened limbs and no further medical or surgical options.
