Cornell University researchers discover extracellular vesicles prevent cellular aging

Cornell University researchers have discovered that extracellular vesicles from embryonic stem cells can prevent cellular aging by blocking oxidative stress. These tiny sacs, coated with fibronectin, trigger a signaling pathway that stops differentiated cells from entering senescence, allowing them to continue growing. The study, published in the Journal of Biological Chemistry, aims to test these anti-aging vesicles in mice and potentially human cells to improve healthspan.
