Cell after apoptosis. Immunofluorescent Light Micrograph of a culture of normal human epithelial cells, showing a cell after apoptosis "genetically programmed death". Cell nuclei are blue; cytoplasm stains red. The green cell (at left) is seen after apoptosis: in which the nucleus and cytoplasm have fragmented into blobs (see photo: G450/044 for this cell before apoptosis). The cell remnants are then eaten by neighbouring cells. Research on apoptosis may provide genetic treatments for diseases such as cancer. Immunofluorescence uses antibodies to attach fluorescent dyes to cell structures. Magnification: x250 at 5x7cm size.
