Flow cytometry was used to study the optical properties of normal urothelial cells in suspension. Narrow-angle light scatter, which is a function of cell size, defined one major and one minor cell population, and 90 degrees light scatter, a function of intracellular structure, showed three distinct cell populations. These properties were displayed as a 2-dimensional dot plot or "fingerprint" which proved to be characteristic and reproducible from one specimen of urothelium to the next. Cell sorting on the basis of these two parameters demonstrated that the small cells of the basal layer occupy the low narrow angle, low 90 degrees light-scatter region; the giant cells of the superficial layer lie in the high narrow angle, high 90 degrees scatter region; and the pyramidal cells of the intermediate layer lie in an intermediate zone. Studies of tissue sections using the galactose-specific, FITC-conjugated Maclura Pomifera lectin (MPA) demonstrated preferential binding to the superficial layers of intact urothelium. In order to quantify the apparent differences in lectin binding between the superficial and basal layers, urothelial cell suspensions were labeled with FITC-conjugated MPA and studied by flow cytometry. The resolution obtained on the basis of light scatter made it possible to quantify the difference in lectin binding to the three morphologically recognized cell types present in normal urothelium.
