Cellular Longevity

Meaning

Cellular Longevity is a precise measure of the functional lifespan and inherent proliferative capacity of individual cells within a living organism, reflecting the cumulative efficiency of intrinsic cellular maintenance and repair mechanisms. This fundamental biological metric is a key determinant of overall healthspan and is inversely correlated with the rate of biological aging and the onset of senescence. Optimizing cellular longevity involves supporting telomere integrity, maximizing mitochondrial bioenergetics, and promoting effective cellular waste removal processes like autophagy.
