The phrase "ageing of cells" is correct and usable in written English.
It can be used in scientific or medical contexts when discussing the biological process of cells becoming older or deteriorating over time.
Example: "The ageing of cells can lead to various health issues, including decreased function and increased susceptibility to diseases."
Alternatives: "cellular ageing" or "senescence of cells".
Telomeres play a key role in the ageing of cells, acting like a clock that limits their lifespan.
In barley (Hordeum vulgare), wide variation in telomere length is observed during the differentiation or ageing of cells.
However, one striking outcome of these studies is that there is a significant, quantitative, passage-associated increase in two heterochromatin markers, HP1β and mH2A, in the nuclei of cells approaching senescence in vitro and, for mH2A, a tight correlation with ageing of cells in vivo (Kreiling et al. 2011).
At this point, the idea that telomeres regulate the aging of cells is only a theory.
If confirmed, this may mean that meditation could help slow the aging of cells.
Besides working on stem cells, it is testing drugs for cancer that influence telomeres, the caps on the ends of chromosomes that help control the aging of cells.
"By studying the mechanism we might be able to learn more about how the age of cells is also locked in," she told the Guardian.
Third, the aging of cells in the test tube is not necessarily the same as the aging of tissues in the body.
Moreover, due to the age-dependence of the rate functions, correlations between the ages of cells in the population develop and divergence from the expected number density (and expected total number of cells) occurs.
Recent findings support the possibility that nonpathological aging of cells may be caused solely by external signals and moreover that this aging might be reversible.
In tomorrow's Science, biologists report the discovery of a second enzyme that can slow the aging of cells.
