Scientific definitions for apoptosis
apoptosis
[ ăp′əp-tō′sĭs, ăp′ə-tō′- ]
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. Also called programmed cell death
Cultural definitions for apoptosis
apoptosis
[ (ap-uhp-toh-sis) ]
The programmed death of a cell. Scientists believe that this process is governed by chemical signals a given cell receives from its neighbors.
