Improved models for animal research

Abstract

Experimental animal models are critical to understand gene function and human disease. Many rodent models are presently available providing avenues to elucidate gene function and/or to recapitulate specific pathological conditions. To a large extent, successful translation of clinical evidence or analytical data into appropriate mouse models is possible through progress in transgenic or gene deletion technology. Despite these significant improvements, major limitations still exist in manipulating the mouse genome. For this reason and to maximize success, the design and planning of mouse models need good knowledge concerning the requirements and limitations of commonly used strategies and emerging technologies. The purpose of this chapter is to provide a current overview of strategies for manipulating the mouse genome. © 2008 Humana Press Inc.
