Large animal models, enhanced by precise genome editing techniques, offer greater similarity to human cardiovascular anatomy and physiology than rodent models for translational research.
Large animal models offer a more anatomically and physiologically relevant platform than rodents for translating basic cardiovascular science into clinical applications.
The human cardiovascular system is a complex arrangement of specialized structures with distinct functions. The molecular landscape, including the genome, transcriptome and proteome, is pivotal to the biological complexity of both normal and abnormal mammalian processes. Despite our advancing knowledge and understanding of cardiovascular disease (CVD) through the principal use of rodent models, this continues to be an increasing issue in today's world. For instance, as the ageing population increases, so does the incidence of heart valve dysfunction. This may be because of changes in molecular composition and structure of the extracellular matrix, or from the pathological process of vascular calcification in which bone-formation related factors cause ectopic mineralization. However, significant differences between mice and men exist in terms of cardiovascular anatomy, physiology and pathology. In contrast, large animal models can show considerably greater similarity to humans. Furthermore, precise and efficient genome editing techniques enable the generation of tailored models for translational research. These novel systems provide a huge potential for large animal models to investigate the regulatory factors and molecular pathways that contribute to CVD in vivo. In turn, this will help bridge the gap between basic science and clinical applications by facilitating the refinement of therapies for cardiovascular disease.
Tsang et al. (Wed,) conducted a review in Cardiovascular disease. Large animal models vs. Rodent models was evaluated. Large animal models, enhanced by precise genome editing techniques, offer greater similarity to human cardiovascular anatomy and physiology than rodent models for translational research.
