Thirty years after a single protein marker opened a window into cellular aging, science has arrived at a richer and more consequential understanding: the cells that stop dividing do not simply fade away, but linger as active agents of inflammation and tissue decay. A new review from Tufts University traces this arc from the 1995 discovery of senescence-associated beta-galactosidase to today's emerging therapies designed to eliminate or silence these cells. What began as a marker has become a mechanism — and a target.
