Your Brain Under the Microscope: The Promise of Stem Cells
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.
The Promise and the Reality of Stem-Cell Therapies for Neurodegenerative Diseases
Jonathan D. Glass, M.D., is leading a clinical trial testing the safety of using adult stem cells to treat patients with amyotrophic lateral sclerosis (ALS), a neurodegenerative disease that remains untreatable. This trial, along with others like it, is just the beginning of a time-intensive process necessary to determine whether the benefits of stem-cell treatments—if there prove to be any—outweigh the risks.
