This is Science Today. Stem cells are providing
new hope for the treatment of neurodegenerative
diseases. A recent University of California, San
Francisco study demonstrates the existence of adult
neural stem cells in the human brain, proving that
the brain has the potential for self-regeneration.
According to Nader Sanai, who led the study, these
findings may one day revolutionize clinical neuroscience
as we know it.
Sanai: Up until now the field of the clinical neurosciences and neurosurgery has predominantly been a field where one attempts to eliminate and restrict damaging disease processes. After that initial intervention there aren't many tools at our disposal for actually reconstituting what was lost. So, here we have perhaps the first tool in a new line of therapies where one would have the possibility of reforming systems or cells that were damaged or lost in a disease process.
