In order to find additional ways to classify bladder cancer, multiparameter analysis with antibodies against urothelial associated-glycoproteins (UAGAb: Uro1, -5, -9, -10; Signet) and cytokeratins (CKAb: KL1, Immunotech) were used in parallel with DNA staining. Single cell suspensions of 21 bladder cancer specimens (4pTaG1, 9pTaG2, 1pT1G2, 2 > pT2G2, 5 > pT2G3) were stained. Preliminary data showed that the proportion of UAGAb positive cells have to be related to the pan-urothelial marker Uro5, since percentage of urothelial cells was variable (30-97%). Phenotypic differences found in different stages of tumor will be described. Selection of tumor cells by UAG did result in higher precision to determine tumor S-phase fraction, and helped select tetraploid tumors. The methodology is best applicable to pTa and pT1-tumors and prospective analysis of these tumors has started.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004847	Epithelial Cells	Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

D005434	Flow Cytometry	Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
