Distribution of testosterone-BSA-FITC specific fluorescence intensity in cells isolated from prostate carcinomas or benign prostate hyperplasia, and morphologically normal prostate epithelial cells, detected by flow cytometry. Fluorescent intensity was calculated as the peak fluorescence difference in cells stained with testosterone-BSA-FITC and BSA-FITC. Bars indicate the mean value. ***: p < 0.001 at least. Results are presented on a logarithmic scale.
