- Test Example 3 Permeability in human small intestinal epithelium
- C ac 0-2 cells which are human colon adenocarcinomas, differentiate spontaneously in culture and form a polarized monolayer of microvilli, such as small intestinal epithelial cells.
- the formation of the film has confirmed the presence of titration (ti gh tj un ction). Therefore, it can be used as a model system for human small intestinal epithelium, and is considered to be the simplest system for evaluating the permeation of drugs through a membrane during oral administration in humans.
- the specific experimental method is as follows.
