    Abstract:
    Flow cytometry and microscopy are equally important in cell analysis. However, few reports have compared the optical data (cell size, internal complexity and fluorescent signal) from flow cytometry and microscopy. In this study, we compared the scattergram from XN-series, a flow cytometry based hematology analyzer with microscopic images of similarly treated leukocytes, and investigated the correlation between the appearance in the scattergram and cell size, internal complexity and fluorescence intensity. Healthy human peripheral blood was analyzed using the XN analyzer. For microscopic comparison, five types of leukocytes (monocytes, lymphocytes, basophils, neutrophils and eosinophils) were isolated from the peripheral blood by centrifugation and magnetic cell sorting, treated with a specific reagent and analyzed using electron microscopy, laser microscopy and confocal laser microscopy. Cell size, residual internal structures and fluorescence intensity correlated with intensity of forward-scattering, side scattering and fluorescent light. In this study, optical data from a clinically used hematology analyzer was clarified using microscopic images.
