Novel Pathway Regulates Timing of Brain-Cell Development

Brain formation involves the carefully timed production of different types of nerve cells by neural stem cells: neurons are produced first, then astrocytes. Making too much of one kind of cell and too little of another at a given time could lead to brain malformations. In the October 6 issue of Cell, researchers in the Neurobiology Program at Children’s Hospital Boston report discovering a new molecular pathway that influences the timing of nerve-cell production.
