University of Veterinary Medicine Vienna A quality framework for cryopreserved rodent disease models: INFRAFRONTIER quality principles in EMMA archiving and distribution Ensuring the quality and reproducibility of biological resources is essential for advancing biomedical research and upholding animal welfare standards. The European Mouse Mutant Archive (EMMA), part of the INFRAFRONTIER research infrastructure, plays a key role in this effort by cryopreserving scientifically validated mutant mouse and rat strains and making them accessible to the global scientific community. To further enhance its processes and promote transparency, INFRAFRONTIER/EMMA has developed a set of ten Quality Principles specifically tailored to the unique requirements of cryopreserved rodent mutant strains. These principles guide EMMA’s workflows by providing a structured yet flexible quality framework across its distributed nodes. They encompass both general standards—such as adherence to the 3Rs (Replace, Reduce, Refine), staff competence, and continuous improvement—and more specific areas including scientific evaluation, data curation, and intellectual property rights. Each principle is presented with contextual background, defined requirements, practical recommendations, and key references. This initiative aims to strengthen the reliability, ethical integrity, and reproducibility of preclinical research resources. en TEXT journal article Wissenschaftlicher Artikel Articolo scientifico Documento PDF Articolo scientifico Text journal article Text Wissenschaftlicher Artikel 2026 2026 Hilke Ehlich Andrew Blease Reva Biju Montse Gustems Fei Song Sabine Fessele Marzia Massimi Konstantinos Bozonelos Vasileios Ntafis Anniina E.
