||Supporting and training the users of CELPHEDIA is an essential objective among the missions of the Infrastructure CELPHEDIA. The centers offer a comprehensive range of training courses and workshops of interest to their users. The trainings are built on the expertise of the centers and contribute also to answer the core teams' needs. The goal is to train and support the users for an efficient use of animal model organisms with respect to the Ethics and animal welfare. Since 2015, new trainings such as a regulatory CNRS training session in ENGLISH for staff developing experimental procedures and projects on "rodents", regulatory and compulsory CNRS training sessions in French for staff developing experimental procedures on either non-human primates, or aquatic vertebrates, as well as an INSERM training session on multiparametric flow cytometry, have been implemented to meet the needs of the scientific community.
