This is defined by cells undergoing sufficient divisions to cause telomere shortening, which elicit a DNA damage response (DDR) and consequentially cell cycle arrest. Read more in our Cellular Senescence eBook Senescence can be induced by various cell stressors such as oncogenes, oxidative stress, ...
Cellular senescence is a state of stable cell cycle arrest. Cells remain metabolically active, but no longer divide or respond to growth-promoting stimuli.
β-gal activation is commonly used as a biomarker for senescent cells. Although β-gal activity is considered a hallmark of senescence, it does not cause the phenomena. Rather, it has been shown that there is an increase in enzymatic activity as the cells enter a senescent state. This hydrol...
Cell senescence is a process that occurs due to telomere erosion or can be induced by various stresses. Senescent cells cease to divide but remain alive, metabolically active and able to secrete many molecules. They also show many hallmarks of senescence, such as enlarged size, increased granulari...
Cellular senescence is a process that results from a variety of stresses and leads to a state of irreversible growth arrest. Senescent cells accumulate during aging and have been implicated in promoting a variety of age-related diseases. Cellular senescence may play an important role in tumor suppr...

senescenceclearance of apoptotic cellsThe clearance of dying cells has become an important field of research. Apart from a significant increase in our understanding of the mechanisms for uptake, cell clearance is a basic mechanism in tissue homeostasis, cancer, resolution of inflammation, induction of...
This is now known as the “Hayflick Limit”. Hayflick discovered that your cells go through 3 phases. This first is rapid cell division called ‘mitosis’. The 2nd is where mitosis slows. And the 3rd stage is ‘senescence’ where the cell stops dividing entirely. They remain alive for a ...
As we grow older, aches and pains can become a chronic part of life. But experts say it doesn't have to—and solutions are on the way.
