title: Your brain under the microscope: the promise of stem cells.
abstract: Until recently, scientists primarily worked with two kinds of stem cells from animals and humans: embryonic stem cells and non-embryonic "somatic" or "adult" stem cells. Scientists are just now beginning to improve their understanding of a third kind: induced pluripotent stem cells. Our authors describe how they were discovered, what they are, and why a growing number of researchers and clinicians believe that they may be one of the keys in helping address various brain disorders.
