Often animals are killed to provide a specific tissue or organ for experimental use. The remainder of the animal is unwanted and disposed of. Archiving and sharing of this material instead can help to reduce the number of animals culled by optimising the use of tissues and organs between scientists with different requirements. The ageing mouse tissue bank, ShARM, hosted by the University of Sheffield is a great example of this in practice.
There is still much to be done to encourage scientists to use archived tissue and ShARM has recently produced a short video to highlight the benefits. It is also offering free tissue until 15 August to allow users to try the benefits for themselves.
