Discovering 'rogue cells': Scientists stop aging in mice

As people get older, their bones become fragile, their minds become dull, and their organs sometimes slowly fail, Newsweek reported.
But now scientists believe that these unpleasant aging processes can be stopped -- at least in mice. researchers at the Mayo Clinic,
, believe they have discovered a "rogue cell" similar to bacteria that can cause most age-related diseases.
these cells are called senescent cells and form over time.
if a person has too many such cells in his body, they will refuse to die and do nothing inside the body, killing other cells they have come into contact with. scientists at the Mayo Clinic
found that they can destroy aging cells to stop or even reverse the harmful effects of rodent aging.
study, published July 10 in the journal Nature Medicine, found that the method could extend the life span of mice by 36 per cent. "This is an exciting study," said Felipe Serra, director of the Department of Aging Biology at the National Aging Institute. "More research is still needed to determine whether compounds, such as those used in this study, are safe and effective in human clinical trials."

" the results of this study suggest that longer life depends on the delay of all age-related diseases.
lead author of the study, Dr. James Kirkland of the Mayo Clinic, told reporters that while the mice lived longer, the researchers did not prolong the vulnerability at the end of their lives. "I think the main thing we need to do is improve our health, not live longer, "
.
extended life may be a good side effect.
