Purging Senescent Cells May Postpone Diseases of Aging, Study Finds - NYTimes.com: Rid of the senescent cells, the Mayo Clinic researchers reported online Wednesday in the journal Nature, the mice’s tissues showed a major improvement in the usual burden of age-related disorders. Mice that had been cleansed of senescent cells from weaning onward did not develop cataracts, avoided the usual wasting of muscle with age, and could exercise much longer on a mouse treadmill. They retained the fat layers in the skin that usually thin out with age and, in people, cause wrinkling.
