Abstract: A filter device is provided which includes a well, at least one top access opening to the well, and a horizontally-disposed filter. The well, which includes an inner surface at least partially defining the well, also includes a first well chamber to accommodate a fluid and a second well chamber to accommodate a fluid. The first well chamber and the second well chamber are separate chambers, and the inner surface at least partially defines the first well chamber and at least partially defines the second well chamber. The at least one top access opening provides independent top access to the first well chamber and the second well chamber, and the horizontally-disposed filter is positioned between and at least partially separates the separate first well chamber and second well chamber of the well.

Abstract: Method and apparatus for processing a cell culture are provided. The method includes establishing a cell culture within a holding device having one or more wells, each well holding a cell culture, and including a well substrate with at least one electrode in contact with the cell culture; periodically applying at least one electrical pulse to the at least one electrode to prevent cells from attaching to and achieving confluence over the at least one electrode while allowing cells to attach to and achieve confluence over other portions of the well substrate; and discontinuing the periodically applying of the at least one electrical pulse to the at least one electrode after cells have achieved confluence over the other portions of the well substrate, and thereafter, monitoring the cell culture to monitor migration of cells over the electrode(s) from the other portions of the well substrate.

Abstract: The present invention provides methods for the assessment of the metastatic potential of cells by measuring the effect of the cells on the impedance of an electrode. Accordingly, the present invention similarly provides methods for establishing indicators of metastatic potential based on a cell's effect on impedance. Such methods may be employed in vitro or in vivo. In some embodiments, the electrode is coated with endothelial or epithelial cells.

Abstract: A method and system for electrically wounding and/or monitoring cell activity in vitro. The invention comprises methods and systems for wounding and/or monitoring cells that place a cell culture on a well that has an exposed electrode. The cell culture can then be wounded and/or monitored using the electrode.
