CD31/PAS double staining for showing VM morphology. a, b, and c demonstrated the typical blood vessels in normal cervix, LSIL, and HSIL, respectively (200×magnification). d, e, and f demonstrated VM channels and typical blood vessels in CSCC (400×magnification). Black arrows indicate typical microvessels with CD31 positive and PAS negative. Red arrows indicate VM channels consisting of cancer cells and basement membrane, with CD31 negative and PAS positive correspondingly.
