New understanding of formation of cilia: Cilia provide mobility to cells, and defects are implicated in many disease

Tiny hair-like structures (cilia) are found on the surface of most cells. Cilia are responsible for the locomotion of cells (e.g. sperm cells), they process external signals and coordinate the correct arrangement of the inner organs during the development of an organism. For proper assembly and function of cilia, they need to be supplied with the appropriate building blocks. Scientists have now identified the mechanism of how Tubulin, the main building block of cilia, is transported within the cilium.
