Primary cilia are antenna-like structures that are present on the surface of most cells in the human body. The cilia are essential mediators of communication between the different cells in the body. If the cilia are defective, this communication is disrupted, and the cells are unable to appropriately regulate several important cellular processes, which ultimately can lead to severe diseases that may affect nearly every organ and tissue in the body, in the developing embryo as well as in the adult.
