Dead stem cells boost brain recovery after injury, study finds

Researchers discovered that transplanted neural stem cells that die in the injured brain actually accelerate healing in surrounding tissue through a "bystander effect." The finding could reshape how scientists design cell therapies for stroke and traumatic brain injury, potentially improving outcomes without requiring cells to survive long-term.
