Apoptosis, known as programmed cell death, is a carefully controlled, energy-dependent process of cell death. Induction of apoptosis results in a cascade of characteristic biochemical events resulting in changes in cellular morphology and death. Cells undergoing apoptosis display blebbing, cell shrinkage, nuclear fragmentation, and DNA apoptosis is a coordinated and often energy-dependent pro-cess that involves the activation of a group of cysteine pro-teasescalled“caspases”andacomplexcascadeofeventsthat link the initiating stimuli to the final demise of the cell.

However, apoptosis should not be considered synonymous with PCD. Analysis of apoptosis morphology in Epstein-Barr virus positive and negative Burkitt's lymphoma cells.

The TUNEL positivity was in all cases confirmed with apoptotic morphology. Results: The inflammatory infiltrate consisted of numerous eosinophils but also a
12 May 2014 Caspase-3 positive apoptotic cells demonstrate morphological features that morphology and cell distribution following induction of apoptosis. 22 Jun 2015 Apoptotic cells show some morphological features including blebs, formation of apoptotic bodies, chromatin condensation with margination of Apoptosis is characterised by a series of typical morphological events, such as shrinkage of the cell, fragmentation into membrane-bound apoptotic bodies and Therefore, cells that have initiated apoptosis may exhibit some of the morphological phenotypes associated with necrosis. Because programmed cell death takes 1 Mar 2015 FIGURE 1: HYPOTHETICAL MODEL OF CELL DEATH REGULATION IN APOPTOSIS. Morphology of apoptosis: Light and electron microscopy Late stage apoptosis is characterized morphologically by cell shrinkage and phagocytosis of the apoptotic cell by macrophages.

Changes in nuclear morphology and in organelle structure as well as specific phenomena at the cell surface
The term ‘apoptosis’ is used to describe sometimes only the morphology, sometimes the underlying mechanism, of a cell-autonomous active process in which a specialised sig-nalling pathway is active in killing the cell and organising its disposal. The term ‘programmed cell death’ has for a long time been used for developmentally occurring cell

The morphology of apoptosis involves changes within the nucleus, within specific organelles (most notably, the mitochondria), and within the plasma membrane. In what was once considered to be the hallmark of apoptosis, the chromatin condenses within the nucleus, as DNA is degraded first into large 30 to 50 kb fragments and then into smaller nucleosomal fragments of 180–200 bp. On the other hand, the relationship between sperm morphology and apoptosis has not been well characterized. A significant negative relationship between the proportions of apoptotic sperm and those of sperm with normal morphology in semen applying the Tygerberg's strict criteria ( Kruger et al.

Each initiator caspase is activated by a unique complex of proteins. Apoptosis is characterised by cell morphological changes, chromatin condensation, DNA cleavage, and nuclear fragmentation.
Apoptosis is a morphologically and biochemically distinct form of programmed cell death that plays an essential role during embryologic development, after birth, and during adulthood. However, deregulation of apoptosis is involved in the pathogenesis of a variety of human diseases. Although there may be alternative molecular pathways that cause apoptosis-like cell morphology, the term apoptosis most often refers to caspase-dependent cell death. The extrinsic and intrinsic pathways activate different initiator caspases.

Apoptosis is the best-characterized form of programmed cell death, but alternative non-apoptotic cell-death pathways important in human physiology and disease pathology are now actively studied. Regarding apoptosis, there are two general pathways, the extrinsic pathways and the intrinsic pathways, depending on whether the molecular factor that initiates the death pathway is extra-cellular or
