Number of Polyploid Giant Cancer Cells and Expression of EZH2 Are Associated with VM Formation and Tumor Grade in Human Ovarian Tumor
Figure 2
VM and EV present in human serous ovarian tumor. (a) EVs in human serous ovarian carcinoma (black arrow, H&E ×200). (b) Endothelial cells in EV were positive for CD31 and PAS staining (black arrows, double staining ×200). (c) VM without basement membrane (black arrow, H&E ×200). (d) VM with basement membrane in human serous ovarian carcinoma (black arrow, H&E ×200). (e) VM without basement membrane was negative for CD31 and PAS staining (large black arrow, double staining ×200) and EVs were positive for CD31 and PAS staining (small black arrow, double staining ×200). (f) VM with basement membrane was negative for CD31 staining and positive for PAS staining (black arrow, double staining ×200).
