Intestinal Fibrosis

The EpiIntestinal tissue model is useful for testing candidate drugs or biologics to treat diseases that are characterized by inflammation of the small intestine.

The Model

EpiIntestinal is a 3D reconstructed tissue model produced from normal, human cell-derived small intestine epithelial and endothelial cells and fibroblasts. The highly differentiated tissue model is produced at the air-liquid-interface (ALI) in easy-to-handle tissue culture inserts. Structural analysis of the tissue model demonstrates columnar shaped basal cells and Kerckring folds. Ultrastructurally, EpiIntestinal exhibits brush borders, functional tight junctions and mucous secreting granules, similar to in vivo tissue.
