Zeng, Shi, Han, Hu, Li, Wei et al. present a metabolic atlas covering 15 hematopoietic cell types from young and aged mice. By screening metabolites that are depleted with age, they identify that uridine treatment can restore function in aged hematopoietic stem cells.
Through metabolic screening, we identified uridine as a potential regulator to rejuvenate aged HSPCs.
