Removing 'retired' cells could reverse ageing

It may one day be possible for over-65s to visit a clinic every few years to receive a rejuvenation shot.
In a new study, scientists at the Erasmus University Medical Center in the Netherlands discovered that purging retired cells from the body can potentially reduce the effects of old age.

The researchers found that mice treated with a special substance designed to remove these dormant cells exhibited several indicators of age reversal including the regrowth of their fur, improved kidney function and the ability to run twice as fast as their untreated counterparts.
"Maybe when you get to 65 you'll go every five years for your anti-senescence shot in the clinic," said study leader Peter de Keizer. "You'll go for your rejuvenation shot."

Senescent cells, which were previously thought to be harmless, are the dormant remains of cells which can no longer be repaired by our bodies.

"It was found that these senescent cells secrete a whole load of junk and they're not just bystanders but have a negative effect," said De Keizer.

Capers for breakfast anyone?   Existing research (from mice) says the compound Quercetin clears out about 50% of senescence cells. Even better, when its combined with dehydration and heat shock it will remove 99.9% of them.

Sleep and activity oxymoronic that and isn't it around 50 that everything starts to fall apart or a huge change?  Like a brother said, everything was going great and then I couldn't walk up the stairs on my hands one day. Speaking of Descent ? (too scary to watch again movie by the way 'we've caves here') decent article thanks for the post.

I thought so as well. Some studies from 2016 I found about scientists reversing aging in mice but nothing like hair growth, kidney function and physical fitness return to elderly mice, who then outperformed younger mice in running races

That dehydration and heat shock sounds like what Native Americans have been to for generations with the sweat lodge.
