Recalibration of signalling factors to more youthful levels in the blood
Rejuvenation might be achieved by the calibration of age-related changes signals found in the blood.
Tissue ageing could be reversed in a matter of weeks with the beneficial signals from the younger animal.
Protein TGF-β1 was found to prevent stem cells from repairing tissue properly in old and young mice.
Scientists were able to reduce TGF-β1 levels and increase oxytocin.
Changing the molecule levels in the blood resulted in promoted rejuvenation and increased neurogenesis.
Recalibration of these signalling factors back reduced the p16 biomarker of cellular senescence.
The study was published in journal Aging.
