TEDD (Tissue Engineering for Drug Development and Substance Testing) is an education, R&D and networking platform promoting the application of 3D organotypic technologies, with the core goal of replacing animal experimentation for therapies development. Based in Switzerland, TEDD is one of its kind in Europe focused on 3D for 3Rs. The community is composed of international members from academia, clinics, industry and non-profits. Information flow, training and education of members is achieved through regular events at the national and international level, including workshops, symposia, company visits, scientific reviews and we provide a platform to generate research consortia, projects and grant applications.
