Live Fruit Fly Brains Reveal Molecular Switch That Wakes Up Dormant Neural Stem Cells

Small (dormant) and enlarged (reactivated) neural stem cells expressing membrane-tagged GFP (green) and the cell cycle marker Cyclin B (red) in the young Drosophila fruit fly larval brain. Credit: University of Plymouth June 6, 2019 (Phys.org) -- Live fruit fly brains have a molecular switch that reactivates dormant neural stem cells (NSCs). Our brains are notoriously bad at regenerating cells th ...
