Until now, the best way of determining how a toxin affects the human body was by testing it on laboratory animals, such as mice, or on individual cells. Unfortunately, the results cannot simply be transposed onto humans. Researchers from Wageningen have now developed a digital laboratory animal. This computer model can predict the effect of a substance on the entire human body. It means that safety tests for promising drugs, for example, could be carried out much more quickly. In addition, the model dispenses with the need for laboratory animals. Another way in which Wageningen UR is helping to improve the quality of life.
