Researchers Identify Key Protein in Stem Cell Aging Process
Scientists from the University of Tokyo and St. Jude Children’s Research Hospital have discovered a non-traditional role for the protein MLKL in the aging of hematopoietic stem cells (HSCs). Typically associated with cell death, MLKL was found to cause mitochondrial damage in HSCs, leading to reduced self-renewal and a shift in cell production. This discovery highlights a new pathway by which aging affects the blood system, offering potential targets for therapies aimed at preserving stem cell function and improving recovery in patients undergoing treatments like chemotherapy.
