Researchers unlock the secrets of cellular aging
A new study has revealed that genetic changes in stem cells of blood, which accumulate over time in the bloodstream, are responsible for the drastic change in blood production following the age 70.
Scientists at the Wellcome Sanger Institute and the Wellcome-MRC Cambridge Stem Cell Institute along with collaborators published the study in Nature.
Longevity. Technology: Have we made a quantum jump in our understanding of one mechanism of aging? The cellular damage we accumulate over the course of our lives increases year by year as a result of telomere loss, epigenetic changes, oxidative stress, and mutations. Double whammy, our ability to repair the damage declines with age. But, given that these processes are gradual, why is there a sudden increase in mortality at 70 years old? [1]\”.
