484-Metabolic Restoration of Stem Cell Fitness
Hematopoietic stem cell (HSC) fitness declines as divisions accrue, shifting BCAA usage from catabolic to anabolic activity. This metabolic drift accelerates the cell cycle and causes lineage infidelity. Supplementing with the metabolite aKIC restores balanced output and regeneration.
