context_page_description: Binucleated cells are cells that contain two nuclei. This type of cell is most commonly found in cancer cells and may arise from a variety of causes. Binucleation can be easily visualized through staining and microscopy. In general, binucleation has negative effects on cell viability and subsequent mitosis.
  They also occur physiologically in hepatocytes, chondrocytes and in fungi.
context_section_description: Binucleated cells can be observed using microscopy. Cells must first be fixed to arrest them wherever they are in the cell cycle and to keep their structures from degrading. Their nuclei and tubulin must next be made visible so that binucleation can be identified. DAPI is a dye that binds to DNA and fluoresces blue. For this reason, it is particularly useful at labeling nuclei. Antibody probes can be used to label tubulin fluorescently. The immunofluorescence may then be observed with microscopy. Binucleated cells are most easily identified by viewing tubulin, which surrounds the two nuclei in the cell. Binucleated cells may be mistaken for two cells in close proximity when viewing only nuclei.
