The NC3Rs: Pioneering better science


We help the research community use the latest science and technology to replace animal studies, providing new approaches for biomedical research and avoiding the time and cost associated with in vivo models. Where the use of animals is still required, we support researchers to design the best experiments so that their methods and findings are robust and reproducible. We provide information and guidance on the latest knowledge to improve laboratory animal welfare.
