Youthful Blood, Old Body: Scientists Rewind Aging Stem Cells by Fixing the Cell’s “Garbage Disposal” System
Aging blood stem cells can be pushed back toward a more youthful, regenerative state by fixing a specific breakdown in their lysosomes, the cell’s internal recycling system. By calming these overactive, damaged lysosomes, researchers restored healthier blood formation, reduced inflammatory signaling, and dramatically improved the ability of old stem cells to repopulate the blood and immune system.
