Integrating pathology into human disease modelling – how to eat the elephant

Mouse models are increasingly being used for the study of human disease, and the generation and functional characterisation of new models is underpinned by high-throughput phenotyping consortia such as the International Mouse Phenotyping Consortium. A new study by Adissu and colleagues, published in Disease Models & Mechanisms, demonstrates the usefulness of histopathology in providing corroborative information and uncovering novel phenotypes in genetically modified mice in a high-throughput screen. Although pathology is recognised as a valuable tool to enhance our understanding of animal disease models, it has also been systematically under-resourced. This Editorial aims to highlight ways in which the gap between the usefulness of pathology and its perceived inaccessibility can be addressed by considering pragmatic solutions for planning, resourcing and accessing pathology expertise. The role of funding agencies, academic centres and journals in ensuring that the value of pathology is fully recognised and is adequately supported and funded is also discussed.
