Short reprogramming reverses blood stem cell aging in mice

Activating reprogramming factors for 16 days in old mice reduced DNA damage, improved blood reconstitution, and dampened transposable element activity.Activating reprogramming factors for 16 days in old mice reduced DNA damage, improved blood reconstitution, and dampened transposable element activity.

Blood-cell telomerase delays premature aging in zebrafish

Boosting telomerase in blood-forming cells extended lifespan in immune-deficient zebrafish and partly restored gut health, operating without major changes in telomere…Boosting telomerase in blood-forming cells extended lifespan in immune-deficient zebrafish and partly restored gut health, operating without major changes in telomere length.

New protein form pushed lab-grown cells to stop dividing

Cell experiments identified a previously unknown protein form that responded to DNA damage and triggered senescence, a state in which cells stop dividing.Cell experiments identified a previously unknown protein form that responded to DNA damage and triggered senescence, a state in which cells stop dividing.
