Research involving animals - MRC

MRC considers the use of animals to be necessary in many areas of biomedical research in order to better understand the living body and what goes wrong in disease. Animal research is essential in the development of safe and effective ways of preventing or treating diseases.

All our animal research is conducted in accordance with UK law and ethically approved by an independent review board. MRC researchers are expected to follow the highest standards of animal welfare.
