Whereas single p63, dual p63/CD31 and dual p63/D2-40 immunoreactivities were completely absent in normal vessels, in occasional CD31 immunostained, D2-40 immunostained or non-immunoreactive lymphatic channels containing tumor emboli, either single p63 myoepithelial immunoreactivity or dual myoepithelial and endothelial immunoreactivities were present (p=.05) (Figure 10A; Figure 10B; Figure 10C) (Table 3). This evidence concerns the gene PECAM1 and neoplasm.
