This figure shows schematic representation of cilia ultrastructure with cross-sections at the level of the basal body, transition fibers, transition zone and axoneme in motile and non-motile cilia. On the left hand side, is an enlarged immunofluorescence micrograph of a single primary cilium on an IMCD3 epithelial cell immunostained for the cilia marker acetylated α-tubulin (blue), the basal body marker γ-tubulin (red), and transmembrane protein (TMEM) 216 (green) which localizes to the transition zone. Scale bar = 1 μm.
