Brain gains seen in elderly mice injected with human umbilical cord plasma

Memory protein that declines with aging also identified in mouse study

mouse hippocampus

YOUTHFUL GLOW  In the hippocampus of a 1-month-old mouse, some nerve cells (red) produce the protein TIMP2 (green), which declines with age and may help keep the brain young. Blue indicates microglial cells.
