Figure 5.

PDEF expression data in samples from benign prostate tissues, prostate intraepithelial neoplasias (PIN) and prostate carcinomas. Negative samples (all tumor cells lacking staining) are shown as green crosses inside the squares projecting out to the left of each graph. The samples showing PDEF expression below thresholds are shown as blue crosses in the main graphs. The red crosses in the graphs represent individual samples that stained above the selected thresholds and therefore scored positive for PDEF expression. The x-axis in these graphs shows different levels of staining intensity i.e. 1+, 2+ and 3+. The y-axis shows percent of positively staining cells in a given tumor sample.
