5 Stem Cells Hear Call of		Injured Tissue, Science
 









In animal models, injected stem cells travel to tissue
injured by stroke, Alzheimer's-like plaques, contusions, or
spinal cord bruises, sometimes traversing long distances.
Several teams reported these surprising results this month at
the Society for Neuroscience annual meeting. No one knows
exactly how stem cells detect these different kinds of damage,
but researchers hope that the cells' migratory powers can be
harnessed to either replace dead tissue or deliver therapeutics
right where they're needed.
