In normal tissues there is a balance between the generation of new cells via cell division and the loss of cells via cell death.

Rights and permissions. About this article. The morphology of apoptosis. Apoptosis: Introduction, Morphologic Changes and Mechanism by Dr. Devesh Mishra. Paraptosis (from the Greek παρά para, "related to" and apoptosis) is a type of programmed cell death, morphologically distinct from apoptosis and necrosis.The defining features of paraptosis are cytoplasmic vacuolation, independent of caspase activation and inhibition, and lack of apoptotic morphology.

(Please Turn on Annotations) Topics Included :- What is Apoptosis ?- Four Important Points about Apoptosis- Apoptosis & Programmed Cell Death- Definition of Apoptosis: Morphology Single cells or groups of cells Cells show intensely eosinophilic cytoplasm and condensed pyknotic nucleus Cells are not surrounded by inflammatory cells Rapidly removed by fragmentation and engulfment by cells Pyknosis: increased basophilia due to shrinkage of the nucleus 16 t he cells shrink rapidly Ahmad Itmezeh 1. Apoptosis: Initiator caspases (2, 8, 9, 10) • Caspase 8 coordinates response to TNF in the induction of inflammation, apoptosis, and necroptosis • Caspase 2 & 10 are alternates 2. Apoptosis: Effector caspases (3, 6, and 7) • Essential executioners to dismantle the cell via proteolytic cleavage Cells undergoing apoptosis show characteristic morphological and biochemical features 6. These features include chromatin aggregation, nuclear and cytoplasmic condensation, partition of cytoplasm and nucleus into membrane bound-vesicles (apoptotic bodies)

Apoptosis is characterised by cell morphological changes, chromatin condensation, DNA cleavage, and nuclear fragmentation.

, 2004 ; Chen et al. , 2006 ). 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.

Programmed cell death is morphologically and biochemically distinct from cell death by injury (necrosis). Unlike necrotic cells, apoptotic cells exhibit compaction

Authors R M Thus, additional analysis using TUNEL or activated caspase‐3 labelling or apoptotic morphology following H&E or PAS staining is required to verify the presence of apoptosis.

Apoptosis has previously been visualized in whole embryos using the vital dyes acridine orange, Nile blue sulfate, and neutral red. In the present study, mouse embryos wer … Apoptosis and morphology in mouse embryos by confocal laser scanning microscopy Methods.

The morphologic hallmarks of apoptosis include chromatic margination, nuclear condensation and fragmentation, and condensation of the cell with preservation of organelles. The process is followed by fragmentation of the cell into membrane-bound apoptotic bodies, which undergo phagocytosis by nearby cells without associated inflammation [10, 11].

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.

If Apoptosis : Definition, Causes, Morphology, Mechanisms (HD) - YouTube.

Apoptosis is characterised by a series of typical morphological events, such as shrinkage of the cell, fragmentation into membrane-bound apoptotic bodies and rapid phagocytosis by neighbouring cells [1]. Internucleosomal fragmentation of genomic DNA has been the biochemical hallmark of apoptosis for many years [2]. Hello everyone! This is my second video on cell injury & cell death. In this video, I discuss about the 2 major types of cell death, Necrosis & Apoptosis.
