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 ...

6 days ago · 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 …

Summary points Apoptosis is a genetically regulated form of cell death It has a role in biological processes, including embryogenesis, ageing, and many diseases The molecular mechanisms involved in death signals, genetic regulation, activation of effectors have been identified Many existing treatments (such as non-steroidal anti-inflammatories and anticancer treatments) act through apoptosis ...

Apr 30, 2024 · 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 ...

Mar 8, 2025 · 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 …

Mar 20, 2024 · Learn about apoptosis in cell biology. Get the definition, understand its importance, and compare apoptosis with necrosis.

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 …

The term apoptosis is proposed for a hitherto little recognized mechanism of controlled cell deletion, which appears to play a complementary but opposite role to mitosis in the regulation of animal cell populations. Its morphological features ...
