Figure 1From: Primary Tumor Vascularity, HIF-1α and VEGF expression in vulvar squamous cell carcinomas: their relationships with clinicopathological characteristics and prognostic impact Representative images of CD34 staining of primary vulvar carcinoma vascularization. (A) Low vascularity (low Chalkley count) and (B) High vascularity (high Chalkley count). Images were taken by a Leica DFC 320 digital camera with a Plan-neofluar 10× objective lens in Axiophot microscope (Zeiss Germany).Back to article page
