Neural Stem Cells Maintain High Levels of Reactive Oxygen Species

For years, the majority of research on reactive oxygen species (ROS) - ions or very small molecules that include free radicals - has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses. However, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have shown for the first time that neural stem cells, the cells that give rise to neurons, maintain high levels of ROS to help regulate normal self-renewal and differentiation.
