Colorized transmission electron micrograph showing apoptosis of human lymphocyte. Apoptosis,a natural process of self-destruction in certain cells,such as epithelial cells and erythrocytes,that are genetically programmed to have a limited life span or are damaged. Apoptosis can be induced either by a stimulus,such as irradiation or toxic drugs,or by removal of a repressor agent. The cells disintegrate into membrane-bound particles that are then eliminated by phagocytosis. Magnification unknown | |
