Scientists thought adult brains couldn’t heal themselves after damage, especially when it came to astrocytes—support cells long believed to be static. But new mouse studies reveal these cells are actually dynamic repair heroes: they create new nuclei and send them via their own extensions to rebuild lost brain connections. This challenges old assumptions that brain recovery is limited once astrocytes are gone, offering fresh hope for treating brain injuries and autoimmune disorders. Using advanced microscopy, researchers tracked the genes involved and found these regenerative astrocytes are…
