Mice were engineered to express OSKM when receiving the antibiotic doxycycline.
OSKM are 4 genes shown to revert cells to pluripotent stem cells in the lab.
Mice fed doxycycline in drinking water - 2 days on, 5 days off.
A number of aging signs halted or even reversed after just 6 weeks.
The treated mice also experienced a 50% increase in their mean survival time.
If treatment was halted, the aging signs returned.
