A simple method for the quantitative evaluation of functional effects of xenobiotics with cultured cells

We present a simple, noninvasive, nondestructive all-purpose method for the quantitative evaluation of functional effects of xenobiotics with cultured cells and the work station for its routine, easy implementation. At present 1 to 150 cells growing in one to six dishes can be studied in parallel or otherwise at time intervals ranging from 10 s to 6 h or more, over periods of time ranging from a few tens of minutes to 3–4 days. Any aspect of cell physiological behavior can be studied (differentiation-dedifferentiation, migration, division, degeneration, death) without preliminary staining and/or fixation provided it results in optically visible changes.
