Cellular senescence - Wikipedia
Cells grow larger, flatten shape and expressed senescence-associated β-galactosidase (SABG, blue areas), a marker of cellular senescence. Cellular senescence is a phenomenon characterized by the cessation of cell division.
Cellular Senescence - Definition, Causes and Effects - Biology …
2017年5月26日 · Cellular senescence is a state in which cells can no longer divide. This permanent state entails benefits and detriments for the organism in which the cells live. Whereas cellular senescence was first attributed to tumor suppression and aging, more recent research has found that it also promotes cancer and tissue repair.
Cellular senescence: the good, the bad and the unknown
2022年8月3日 · Cellular senescence is a ubiquitous process with roles in tissue remodelling, including wound repair and embryogenesis. However, prolonged senescence can be maladaptive, leading to...

2024年6月20日 · Cellular senescence, when cells become irreversibly growth arrested after a period of in vitro cell proliferation or in response to sublethal stress or oncogene expression (1, 2), plays a role in aging phenotypes and age-associated diseases (1).
Cellular senescence: when bad things happen to good cells
Cellular senescence is a multifaceted process that arrests the proliferation of cells that are at risk of neoplastic transformation. Many stimuli elicit a senescence...
Cellular senescence: Current Biology - Cell Press
2022年5月23日 · Cell senescence acts as a potent tumour-suppressive mechanism limiting the proliferation of cells at risk of malignant transformation and supports the repair of acute tissue damage, but also represents a key driver of ageing and age-related diseases.
Cellular senescence in aging and age-related disease: from …
Cellular senescence, a process that imposes permanent proliferative arrest on cells in response to various stressors, has emerged as a potentially important contributor to aging and age-related disease, and it is an attractive target for therapeutic exploitation.
Mechanisms and Regulation of Cellular Senescence - PMC
Cellular senescence entails a state of an essentially irreversible proliferative arrest in which cells remain metabolically active and secrete a range of pro-inflammatory and proteolytic factors as part of the senescence-associated secretory phenotype.
