Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to characteristic cell changes (morphology) and death. [2] These changes include blebbing, cell shrinkage, nuclear fragmentation ...

细胞凋亡 （英語： apoptosis，源自 希臘語： απόπτωσις，有“堕落、死亡”之意），是一种程序性细胞死亡，发生在多细胞生物和一些真核单细胞微生物（如酵母）中。在细胞凋亡过程中，一些生化事件导致特征性的细胞形态变化，包括起泡、细胞收缩、核碎裂、染色质凝聚、DNA 碎裂和 …

4 天之前 · Those cells apoptose, giving you the fingers. There are human conditions where that ceases to where apoptosis just does not happen and people are born with web feet.

The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis is considered a vital component of various processes including normal ...

The cells of a multicellular organism are members of a highly organized community. The number of cells in this community is tightly regulated—not simply by controlling the rate of cell division, but also by controlling the rate of cell death. If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell …

The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis is considered a vital component of various processes including normal cell turnover, proper development and functioning of t …

Philosophers have spent many centuries searching for the meaning of life, but in recent decades cell biologists have become even more fascinated by the meaning of death. Apoptosis describes the orchestrated collapse of a cell characterised by membrane blebbing, cell shrinkage, condensation of chromatin, and fragmentation of DNA followed by rapid engulfment of the corpse by neighbouring cells ...

2024年4月30日 · First identified in the 1970s, apoptosis was considered parallel to mitosis. Many years later, apoptosis is defined as the ATP-dependent, enzyme-mediated, genetically programmed death of cells that are either no longer required or pose a threat to the organism. Apoptosis results when the cytoskeleton (by proteases) and DNA (by endonucleases) break down through several pathways that are ...

2025年3月8日 · Apoptosis, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged …

SYNTHÈSE DES DONNÉES ET CONCLUSIONS : L’apoptose est caractérisée par des modifications morphologiques et biochimiques distinctes de celles de la nécrose cellulaire. Différentes étapes de la transduction des signaux et des facteurs de la transcription peuvent favoriser ou inhiber l’apoptose.
