Representative immunostaining of CD31. (a) CD31 positive vascular proliferates (asterisk) in palatine tonsil tissue (positive control). (b) High number (>5/HPF) of CD31 positive vascular proliferates (asterisk) between tumor cells of primary colonic cancer (arrow). (c) Low number (<5/HPF) of CD31 positive vascular proliferates (asterisk) between tumor cells of primary colonic cancer.
