During aging, cells display a senescence-associated secretory phenotype (SASP) that transforms normal physiology into pathophysiology of a tissue/organ, leading to its dysfunction. Similarly, the accumulation of senescent bone cells and their dysfunction leads to skeletal morbidity. Therefore, factors ...
Cellular senescence is stable cell cycle arrest linked to aging and cancer and other disease states, including those associated with inflammation. It is induced by DNA damage, oncogenic signaling, and telomere shortening.
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. A wealth of information about senescence...
Cell senescence is a biological process that progresses with aging and is believed to be a key driver of age-related diseases. Senescence, a hallmark of aging, also demonstrates its beneficial physiological aspects as an anti-cancer, pro-regenerative, homeostatic, and developmental mechanism. A ...

Applying these ideas, we critically examine current evidence for a role of cellular senescence in aging and age‐related diseases. We also discuss the differential impact of longevity interventions on senescence burden and other types of age‐related damage. Finally, we propose a model on the role...
Within the past five years technological advances like lineage tracing of cells in model organisms, intra-vital microscopy, nucleic acid sequencing at the single cell level, and high resolution mass spectrometry have allowed to study aging and senescence of individual skin cells within the tissue ...
