[The value of measuring membrane potentials of urothelial cells using cytofluorometry in the study of tumors of the bladder. Preliminary analysis]

In the context of investigation of a prognostic marker applicable to bladder tumours, the authors propose the cytofluorometric study of the membrane potential of malignant urothelial cells using a molecular probe, 3,3' dihexyloxacarbocyanine. This preliminary study demonstrated a significant increase in the membrane potential of malignant urothelial cells in comparison with normal cells, which leads the authors to propose this cellular parameter as a new tool in the prognostic evaluation of bladder tumours.
