title: Experimental Rat and Mouse Carotid Artery Surgery: Injury & Remodeling Studies.
abstract: In cardiovascular research, translation of benchtop findings to the whole body environment is often critical in order to gain a more thorough and comprehensive clinical evaluation of the data with direct extrapolation to the human condition. In particular, developmental and/or pathophysiologic vascular growth studies often employ in vitro approaches such as cultured cells or tissue explant models in order to analyze specific cellular, molecular, genetic and/or biochemical signaling factors under pristine controlled conditions. However, validation of in vitro data in a whole body setting complete with neural, endocrine and other systemic contributions provides essential proof-of-concept from a clinical perspective. Several well-characterized experimental in vivo models exist that provide excellent proof-of-concept tools with which to examine vascular growth and remodeling in the whole body. This article will examine the rat carotid artery balloon injury model, the mouse carotid artery wire denudation injury model, and rat and mouse carotid artery ligation models with particular emphasis on minimally invasive surgical access to the site of intervention. Discussion will include key scientific and technical details as well as caveats, limitations, and considerations for practical use for each of these valuable experimental models.
