The shortening of telomeres is associated with aging-dependent tissue degeneration, stem cell depletion, and organ failure. By reactivating telomerase and lengthening telomeres in old, telomerase-deficient mice, the degeneration processes can be reversed, restoring damaged tissues to almost full functionality.M.
