Abstract—A new method of double immunofluorescence analysis by flow cytometry is developed to evaluate the quantitative expression of the mesenchymal marker vimentin in epithelium cells of a solid tumor, which in turn is a mixture of different histogenesis cells. The method has a number of evident advantages compared to the clinically used immunohistochemistry technique for marker investigation: the intralaboratory precision of the results, gentle preanalytical preparation, lack of subjectivity in the interpretation of the results, and integral evaluation of the markers expression in a large number of cells from a large volume of the tumor tissue sample (≥5000 cells from a sample of ≥2 cm in diameter).
