Cancer cells of ovary. Coloured Scanning Electron Micrograph (SEM) of carcinoma cancer cells of the human ovary. Known as endometrioid carcinoma because these cells resemble carcinoma of the uterus. Two types of cells are seen: some ciliated cells with tufts of cilia (yellow); abundant secretory cells with microvilli (purple). A mucus secretion (white) is visible. These cells are cuboidal andor columnar in shape, with irregular and proliferative growth. Carcinomas grow on the epithelial surface of body organs. It is a common ovarian cancer which can spread and may be fatal. Magnification: x500 at 6x7cm size.
