Animal Alternatives

According to the Institutional Animal Care and Use Committee Guidebook:

There is increasing public interest in exploring alternatives to the use of animals in research and testing. IACUCs regularly consider the question, "Is there an alternative to using live animals in this proposal?" Some suggest that the only acceptable alternatives are those that completely replace animals, while others have less restrictive definitions. The definition of alternatives that allows a degree of common understanding was developed by Russell and Burch, and is referred to as the three "Rs"- replacement, refinement, and reduction. For this discussion, the term "alternatives" refers to systems that do not employ whole live animals.

Alternatives to the use of animals include in vitro model systems. For example, isolated organ preparations, such as the perfused heart, represent in vitro models. More commonly, in vitro systems are thought of as cell, tissue and organ cultures. The source of the tissue may be primary tissue or cell lines obtained invasively or non-invasively. Tests have been developed using in vitro systems for the evaluation of cytotoxicity, inflammation, genotoxicity, and target organ toxicity among others. A third alterative is the use of nonbiological models systems. These include chemically-based systems, physical models such as hemodynamic flow chambers or computer simulations. More mechanistic models are being developed such as quantitative structure-activity responses, linear modeling relationships, and three dimensional computation models. As more data become available, an expansion in this area is anticipated.
