Apoptosis (from Greek falling off) is a term coined by Kerr, Wyllie and Currie in 1972 to describe a form of cell death associated with peculiar morphological changes. They contrasted apoptosis with necrosis, in which large numbers of cells undergo destruction and elicit a regional inflammatory response. In contrast, in apoptosis individual cells die and are being removed quickly, without inflammation, making their demise often difficult to detect. The initial concept of apoptosis was exclusively related to a morphological phenomenon.
