Digestive Disease Week® (DDW) 2025 features 400 sessions over four days. Below, we’ve compiled a selection of must-see sessions for basic scientists so you can bring back the latest updates in stem cells, microbiome, inflammation and more. We’ve grouped basic science sessions within the AGA Basic Science Zone for convenient convention center navigation. Each day features a theme catered to specific areas of research.
