Expression of MR-1 protein in human ovarian tissues and ovarian cancer cell lines (Left to right: magnification = × 40, ×200, and × 400). (A) Ovarian epithelial cells from cysts were negative for MR-1. (B) Serous papillary ovarian carcinoma cells stained positive for MR-1 in the cytoplasm and nuclei (bold arrow). (C) SKOV-3 cells showed strong cytoplasmic and nuclear staining for MR-1 (dashed arrow).
