Mice Brains Can Fix Themselves.
Researchers have found a way to help the brain replace damaged neurons
in mice. The work could lead to therapies for spinal cord injury as
well as Alzheimer's, Parkinson's and other neurodegenerative
diseases.They induced the birth of new cells by killing nearby neurons
in mice,
which set off a cascade of events that led to stem cells, also called
precursor cells, producing new neurons in the cerebral cortex. If
scientists can turn this into a therapy for humans, it would mean that
patients could literally heal themselves with stem cells already
present in their brains.By Kristen Philipkoski. [Wired News]
