A device useful for the in vitro study of cell migration across a monolayer of epithelial cells while simultaneously measuring the transepithelial electrical resistance of the epithelial monolayer is provided and is characterized as including at least three components, a cylinder, a chamber and a punch. The cylinder is designed for tissue culture, the chamber provides a controlled space and/or environment for the cylinder and the punch is provided to cut the epithelial monolayer and its substrate. |
