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

Morphology · Microscopy · Immunostaining Introduction The mode of cell death referred to as apoptosis, and now deWned by a variety of techniques, including biochemistry, Xow cytometry, and imaging was originally deWned based solely upon morphological criteria. In 1972, Kerr et al. (1972) introduced the neologism “apoptosis” to describe a Download Citation | Hacker G.. The morphology of apoptosis. Cell Tissue Res 301: 5-17 | The concept of apoptotic cell death as an essential part of the development and life of complex organisms Too much apoptosis causes cell-loss disorders, whereas too little results in uncontrolled cell proliferation, namely cancerous tumors. Not all forms of PCD share the characteristic shapes (the morphology) and sequences of apoptosis, but all types of PCD are highly regulated processes.

(2017-08-28) Apoptosis Pathology, Pathway, mechanisms In this video we talk about #apoptosis apoptosis is a programmed #cell death pathway by which the organism gets rid Apoptosis is a representative morphology of programmed cell death (PCD) which occurs within a developmental context in response to a definable physiological stimulus and requires de novo gene expression. However, apoptosis should not be considered synonymous with PCD. Analysis of apoptosis morphology in Epstein-Barr virus positive and negative Burkitt's lymphoma cells. Ishii H(1), Gobé GC, Joshita T, Kurabayashi Y, Hosomura Y, Kameya T. Author information: (1)Department of Pathology, Kitasato University School of Medicine, Sagamihara, Japan. 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 PubMed 2011-03-10 · Background Apoptosis is the primary means for eliminating unwanted cells in multicellular organisms in order to preserve tissue homeostasis and function.

The morphological events of apoptosis are rapid and the fragments are quickly phagocytized, considerable apoptosis may occur in some tissues before it is histologically apparent. This method detects the later events of apoptosis, so cells in the early phase of apoptosis will not be detected.
