Experimental models of arteriogenesis: differences and implications.

Abstract

Cardiovascular and cerebrovascular disease represent the two most common causes of mortality and morbidity in western countries, and the treatment for these is generally by the mechanical restoration of blood flow in the affected tissues. Stimulation of collateral artery growth (arteriogenesis) provides a potential alternative option for the treatment of patients suffering from occlusive artery disease. Therefore, researchers have established several angiogenesis and arteriogenesis animal models to investigate basic mechanisms and pharmacological modulation of collateral artery growth. The authors highlight the most important aspects of vascular growth, discuss different methods and techniques for examining the process, and review the advantages and disadvantages associated with the animal models available for studying this phenomenon.
