Metastatic Carcinoma Mammary Epithelial Cell Nucleus (video) Arizona State University Loading video... Caption This video shows optical density regions in a metastatic carcinoma mammary epithelial cell nucleus (scale bar = 5 microns). The light gray haze depicts cytoplasm. The nuclear membrane is blue, low density regions of chromatin are green, moderate density regions are yellow, high density regions are orange, and nucleoli are magenta. Opacity of nuclear membrane (in blue) has been deliberately decreased to enable viewing of nuclear interior.
