Vesicles from Young Mice Alleviate Signs of Aging in Older Animals

In a study published today (October 19) in Science Advances, researchers report that they have temporarily delayed or reversed some of these age-related changes in mice using extracellular vesicles (EVs) derived from younger animals’ stem cells. Just two weeks of treatment increased older mice’s physical strength, triggered signs of regeneration in several tissues, and reduced certain organs’ biological age as measured by epigenetic biomarkers.
