Please check out the news story on “Cilia guide neuronal migration inÂ developing brain,” illustrating the dynamic role played by cilia. Cilia are tiny hair-like structures on the surfaces of cells, but in the brain they are acting more like radio antennae.
In developing mouse embryos, Emory and UNC 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.
The Developmental Cell paper is here. As a bonus, we have a video featuring two of the paper’s authors, geneticist Tamara Caspary and “Neurotypical?” blogger Laura Mariani, a graduate student in Caspary’s lab.
