Work-life balance: Brain stem cells need their rest, too
“Early to bed, early to rise, makes you healthy, wealthy & wise” Benjamin Franklin
~ Uncle Russ
Stem cells in the brain remain dormant until called upon to divide and make more neurons. However, little has been known about the molecular guards that keep them quiet. Now scientists from the Salk Institute for Biological Studies have identified the signal that prevents stem cells from proliferating, protecting the brain against too much cell division and ensuring a pool of neural stem cells that lasts a lifetime.
