An automated microphotometric system has been designed for the successive assessment of a maximum number of parameters from individual cells. The hardware and software elements are described as well as the various photometric functions that can be performed. The aim is to obtain a multiparameter analysis of morphology, cytochemistry, cell surface characteristics, and metabolic activity including cell cycle characteristics for any set of cells selected from a sample. The combination of DNA synthesis rate determination in a really quantitative approach with the analysis of features of nuclear chromatin texture opens up a new field for associating morphology with functional properties. Examples of application are presented to demonstrate the applicability of the system in a heterogeneous cell population of a very limited sample size. For this purpose, human peripheral blood cells grown in diffusion chambers in preirradiated mice were investigated. It is shown that, depending on their functions, different cell types may have quite different nuclear-to-cell area ratios. Further, a crude morphological parameter, such as the degree of basophilia of Giemsa-stained cells, may be associated with the rate of DNA synthesis, thus bearing information on the replicative activity of a cell. Cell surface properties related to the leukemia-associated cALL antigen are investigated in a human-derived cell line and correlated with cell-cycle characteristics. It is concluded that different antigenic sites rather than cell-cycle dependent differences of antigen density account for the outcome of a bimodal distribution.
