Apoptotic Cell Biology: Clearance and Mechanisms

The total number of cells in every multicellular organism is fundamentally fixed to a specific range. A type of programmed cell death happens in such organisms to effectively control the number of cells. This programmed cell death is called apoptosis. Characteristic cell changes and eventually death happens in cells due to certain biochemical events. It is a carefully controlled, energy-dependent process. An average adult human loses between 50 and 70 billion cells each day due to apoptosis...
