Old Human Cells Rejuvenated With Stem Cell Technology:Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development.
The study found that inducing old human cells in a lab dish to briefly express these proteins rewinds many of the molecular hallmarks of aging and renders the treated cells nearly indistinguishable from their younger counterparts.
"We've wondered for some time if it might be possible to simply rewind the aging clock without inducing pluripotency. Now we've found that, by tightly controlling the duration of the exposure to these protein factors, we can promote rejuvenation in multiple human cell types".
