Cilia guide neuronal migration in developing brain

Monday, November 12, 2012 - 15:21 in Biology & Nature

A new study demonstrates the dynamic role cilia play in guiding the migration of neurons in the embryonic brain. Cilia are tiny hair-like structures on the surfaces of cells, but here they are acting more like radio antennae. In developing mouse embryos, researchers were able to see cilia extending and retracting as neurons migrate. The cilia appear to be receiving signals needed for neurons to find their places.
