AAN: Smarter mice

One of the first plenary talks here at the AAN meeting was on stem cell treatments for neurological diseases, given this morning by Steven Goldman of the University of Rochester Medical Center in Rochester, NY. Goldman talked to a bulging conference hall about his labs work on progenitor cells in the brain – cells born in the mammalian brain throughout life that are destined to become neurons or glia.

They’re more common in the brain than you might think – about 3% of cells in the white matter are progenitor cells.
