Epithelial Cell
Epithelial Cell — A cell type forming the lining of body surfaces and organs, commonly used in peptide wound healing, barrier function, and antimicrobial research.
What Is an Epithelial Cell?
Epithelial cells line body surfaces (skin, gut, airways, blood vessels) forming barriers between external and internal environments. Epithelial cells are primary targets for peptide drug delivery (oral, nasal, pulmonary), produce AMPs for mucosal defense, and are studied in Caco-2 permeability assays.
Context
- Caco-2: Human intestinal epithelial cell line. Gold standard for peptide permeability prediction
- AMP production: Airway and intestinal epithelium produce defensins and LL-37
- Tight junctions: Paracellular barrier that peptide enhancers transiently open for absorption
