Figure 1. Annexin A2 immunostaining in human ovarian tissues and omental tissues.

Annexin A2 immunostaining is present in the epithelial cells of normal surface epithelium (A), serous cystadenomas (B) and serous borderline ovarian tumors (C). Annexin A2 immunostaining is present in membrane and cytoplasm of ovarian cancer cells and cancer associated stroma of stage 3 serous ovarian cancer tissues (D). Annexin A2 immunostaining is observed in peritoneal cells of the omentum (E) and serous ovarian cancer cells located adjacent to the peritoneal cells in omental implants (F). Insert in (A) is the negative control with no primary antibody. Magnification bar = 100 μm for all images.
