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.
