Aging Decoded: 7-Million-Cell Atlas Maps Coordinated Decline Across 21 Organs
Researchers mapped nearly 7 million cells from 21 mouse organs at three ages to create the most detailed aging atlas yet, finding that aging proceeds in a synchronized, body-wide fashion with about a quarter of cell types changing in abundance and notable sex differences; the study also identified shared DNA-regulatory hotspots and cytokine-linked changes that could become targets for therapies aiming to slow aging across multiple organs.
