Why aren't alternatives, like cell culture or computer models, used instead of animals?

Alternatives to the use of whole living animals are being developed constantly, and significant progress has been made in this area over the past 20 years. Animal cell culture lines and computer programs have been substituted in some areas of research and their use has contributed to the decrease in the use of live animals.

However, whole animals continue to be required in many areas of research where the complicated, multiple- system interactions and effects mentioned above must be assessed.
