Centriole maturation and transformation to basal body

Centrioles and basal bodies are fascinating and mysterious organelles. They interconvert and seem to be crucial for a wide range of crucial cellular processes. However, intense research over the last years suggested that centrioles/basal bodies are essential mainly for the generation of cilia. Although a neglected organelle over a long time, interest in the primary cilia was recently rekindled by the notion that they are affected in a number of human diseases. Cilia formation is an intricate process that starts with the transformation of centrioles to basal bodies and their docking to the apical plasma membrane. Disturbance of basal body formation thus might cause ciliopathies. This review focuses on the formation of basal bodies in mammalian cells with an emphasis on basal bodies sprouting a primary cilium.
