Researchers Discover Dynamic Behavior of Progenitor Cells in Brain

Monitoring progenitor cells in the brains of living mice, researchers discover these cells remain highly dynamic in the adult brain. Progenitor cells can transform into cells that insulate nerve fibers and help form scars that aid in tissue repair, study suggests.
