Matrix-freies 2D-Organoidmodell zur Erforschung der Darmbarrierefunktion
摘要
2D organoid monolayers cultured on Transwells enable polarized growth and recapitulate the cellular diversity and barrier function characteristics of the human duodenum. The common practice of pre-coating the Transwells with basement membrane extract (BME) is not necessary and instead, adds an additional diffusion barrier. BME-free 2D organoid models are more physiologically relevant for studying intestinal barrier function and help to reduce animal-derived materials in line with the 3R principle.
