The Hands-on Lab Training: In Vitro Lung Models 2025 took place on 6 and 7 November 2025 at Epithelix in Geneva, Switzerland. This two-day training covered the practical use of static and dynamic in vitro 3D respiratory tissues and exposure devices for evaluating acute and repeated dose inhalation toxicity, as well as efficacy testing.

The training began with a half-day of lectures introducing key concepts, followed by one and a half days of intensive hands-on sessions.

Target audience
This training was intended for researchers, laboratory staff, and professionals seeking practical experience with in vitro respiratory models and inhalation exposure systems.
