Neural regeneration from stem cells

Stuart Scott writes "It appears that these researchers may be on to something very interesting. http://www.hhmi.org/news/stevens2.html"

Editor's note: What Stuart is referring to is the news in a press relase from the Howard Hughes Medical Institute (2 May 2002), which begins:

Researchers have discovered that astrocytes ó brain cells once thought to be little more than a component of the supportive scaffold for neurons ó may actually play a starring role in triggering the maturation and proliferation of adult neural stem cells. The studies also suggest that growth factors produced by astrocytes may be critical in regenerating brain or spinal tissue that has been damaged by trauma or disease.
