Programmed cell death (PCD) is a significant mechanism in both development and homeostasis in adult tissues for the elimination of either superfluous, infected, transformed or damaged cells by the launch of an intrinsic suicide program. One form of PCD is apoptosis, which is distinguished by the maintenance of intact cell membranes during the suicide process to allow adjacent cells to engulf the dying cell so that it does not release its contents and trigger a local inciting reaction. Cells undergoing apoptosis usually display a characteristic morphology, including fragmentation of the cell into membrane-bound apoptotic bodies, nuclear and cytoplasmic condensation and endolytic cleavage of the DNA into small oligonucleosomal fragments (Steller, 1445).
