Cellular Healthspan

Meaning

The duration for which a cell maintains robust functional integrity, proliferative capacity, and resistance to stress before entering a state of senescence or programmed death. It represents the quality of cellular life, directly correlating with the overall healthspan of the organism. Maintaining a high cellular healthspan is paramount for preserving tissue and organ function, particularly in hormone-producing glands and cognitive centers. This biological metric is a key focus in longevity medicine, moving beyond mere cellular survival to active, high-quality function.
