Research methods that do not involve the use of nonhuman animals

There are a variety of methods of experimentation which do not require the use of animals. There are currently a number of databases of such methods for a wide array of purposes. This includes education and cosmetics testing, but also basic scientific and biomedical research. Some of them use mathematical and computer models. These in silico techniques (computer-based methods such as computer simulations) can be used to predict the biological activity of substances and can be used in biochemical, physiological, toxicological, and behavioral studies.

Other methods that do not use animals include in vitro, which can be used to study interactions at a very small scale. It can be used at a subcellular level, or at the level of creating entire organs to study.

There are also methods that use brain scanning instead of experiments on primates, or use human tissue for examination.

Changing the current animal research paradigm and implementing these methods would be a great advance to eliminate much animal suffering and death. However, there are many barriers and obstacles that may prevent these methods from becoming the norm.

Defenders of animal experimentation commonly claim that these obstacles are what make this practice unavoidable and so advocate that it continue indefinitely, thus discouraging any agenda to make possible it may come to an end one day.1 The truth is, though, that very little effort and few resources are spent in the development of methods that do not use nonhuman animals. If more work were done on this, scientific obstacles to new methods of research could be overcome.

Funding can be a further problem in advancing the use of research methods not using animals. The research in this area is often carried out in the interest of creating techniques that are considered advanced, instead of as a way of ending the use of animals in scientific studies. It’s a common way of thinking that it is a waste of time and resources to invest in methods not using nonhuman animals because those efforts could be invested in doing actual research with animals that might bring about results directly. As this speciesist attitude continues, animal experimentation goes on and on without there being much motivation to change it. The reason for making such a choice is simply that nonhuman animals are not seen as mattering in any significant way compared to humans. Otherwise, the harm they suffer because they are used in laboratories would be considered as significant as the harms the experiments are supposed to alleviate or the benefits they are supposed to bring about.

In fact, an important part of the funding of research to develop methods without animals comes from people concerned with animals who want to see the end of the use of animals in laboratories. Examples of this are FRAME, the Lord Dowding Fund, the Dr Hawden Trust and the Humane Research Trust. Recently, other bodies such as the MRC, the BBSRC and NC3Rs have also offered some funding for research with the goal of developing research methods that do not use nonhuman animals, though the burden of this effort has traditionally been on groups that defend animals.

There are additional obstacles to the development and implementation of animal-free research methods. Problems may also be caused by legislation and policies driven by an attitude of unwillingness to question this paradigm. In the field of cosmetics experimentation this occurs in a very clear way. The EU and India have forbidden this practice, yet it is compulsory in other places, even though the bans that do exist show that cosmetics experimentation on animals is not necessary.2

Something similar is seen with biomedical research. Regulatory bodies dealing with it may simply not be willing to change. This is exemplified by the difficult requirements for introducing new methods to replace animal testing. They are much harder to meet than requirements for procedures that use nonhuman animals. These bodies claim the additional regulations are due to concerns with safety or liability of new methods, but these concerns appear especially when the methods do not involve nonhuman animals. International bodies must also be convinced that the new methods are acceptable. For these reasons it can be difficult to get regulatory bodies to implement change.3

Despite this, a number of methods without using animals have been developed for research, testing, and education.4 There are so many that they cannot all be listed here. But below are a number of databases in which these methods can be found.

Notes

1 This argument has been used for a very long time by those arguing for speciesism in order to justify animal experimentation. See for instance: Paton, W. (1984) Man and Mouse, Oxford: Oxford University Press; Cohen, C. (1986) “The case for the use of animals in biomedical research”, New England Journal of Medicine, 315, pp. 865-870. In addition, is commonly used in the literature aimed at convincing the public that research methods that do not use nonhuman animals are not valid. See for instance: American Association for Laboratory Animal Science (2003) The use of animals in biomedical research: Improving human and animal health, Memphis: American Association for Laboratory Animal Science [accessed on 25 May 2014].
