For instance, the nuclei of live cells are stained with a fluorescent dye and the cells are tracked using fluorescent imaging, although this type of approach has the potential disadvantage that excitation of fluorescent dyes in cells causes phototoxicity, hindering accurate characterization of cells. In another approach, non-fluorescent imaging, for example, phase contrast or differential interference contrast (DIC) imaging, is used to visualize cells and live cell movies are used for cell tracking , although the approach has never been used to analyze large numbers of cells.
