Primary cilia occur in G0 or early G1 phase and disappear before cells enter mitosis18. Primary cilia assembly involves several successive stages, including maturation of the mother centriole into a basal body, formation of ciliary vesicle, recruitment of tau-tubulin kinase 2, removal of centriolar...
