Why can’t alternatives such as computer models and cell cultures replace animal research?
Computer modeling, cell cultures and some alternative research methods can be excellent avenues for reducing the number of animals used. These methods are best used to screen substances and to determine their toxicity in early stages of investigation. This reduces the total number of research animals needed. The final test, however, must be done in a whole, living system. The most sophisticated technology available today cannot mimic the complicated interactions among cells, tissues and organs that exist in humans and animals. Scientists must understand these interactions before introducing a new treatment or substance into humans.
