Highly abundant “chambers” containing small, round cells (arrows) or clusters of cells (asterisks) in ovarian tissue. They were present in borderline ovarian cancer (a-c) and high-grade serous ovarian carcinoma (d-h) tissue. In a proportion of “chambers” the small, round cells were NANOG-positive and were stained brown. (Light microscope: a-c, magnifications 200x or 1000X; inverted microscope: d-h, magnifications 40x and 100x). Legend: brown-NANOG-positivity, blue-nuclei after HE staining. Red Bar: 100 μm for a-d and 50 μm for e-h
