title: Cytotoxicity detected by image analysis: A new method for the quantification of survival, mortality, recovery and growth of mammalian cell cultures.
abstract: The use of in vitro methods is increasingly recommended for the assessment and evaluation of cytotoxic effects resulting in cell damage. In most cases, cellular response and reaction of cell populations is determined by endpoint measurements. Even if a battery of such test systems is applied, information about the dynamics of cell damage and recovery is obtained only in part. However, phenomena of damage and recovery can be followed by observing the fate of individual cells and their progeny in culture over several days, which means over several cell cycles, by using light microscopy combined with image analysis. We have developed a recording system for such continuous observation and registration of toxic effects, based on image analysis. Growth rate, generation time, delay or shifting of cell cycle, identification of the progeny (pedigrees) and cellular locomotion can be recorded simultaneously.
