Aging Explained: Telomeres, Stem Cells, and Longevity
3 months ago
- Aging is driven by telomere shortening and stem cell loss.
As telomeres shorten with each cell division, chromosomes become unstable, leading to cell death and depletion of stem cells, which are essential for tissue repair and regeneration. - Stem cell attrition leads to disease and organ decline.
The gradual loss of stem cells weakens immunity, reduces the body’s ability to heal, and contributes to many chronic diseases associated with aging. - Future therapies may transform how we age.
Advances in stem cell technology, gene repair, and regenerative medicine may allow scientists to restore damaged tissues and potentially extend healthy lifespan.
