OtoBiology Leiden attended the ARO 2026 conference in Puerto Rico! Heiko was invited to present our developmental human inner ear transcriptomic atlas at the Presidential Symposium and also gave a talk on inner ear organoids as a preclinical in vitro model. Winnie and Esther both presented posters, which attracted a great deal of attention. It was inspiring to hear about and see the work of our international colleagues, the inner ear field is really moving forward! We thank the organizers for a fantastic conference and hope to be there again next year!
