Primary cilia (PC) are sensory organelles that function as cellular antennas, transmitting signals between the extracellular and intracellular spaces in many vertebrate tissues. The cell generates and assembles PC through a highly regulated process called ciliogenesis. This complex process is involved in several physiological functions, including embryonic development, locomotion, cell cycle regulation or energetic homeostasis control. In general, when a cell finishes its cell division, the oldest centriole usually migrates to the plasma membrane and becomes a basal body that gives rise to the formation of a cilium. For this reason, the presence of cilia is incompatible with cell division, so when a cell is going to divide, the cilium and the basal body disappear. Ciliogenesis is triggered by various stimuli, all of them related to cell cycle blockade. This cell cycle, and ciliogenesis induction, can be observed by: (1) the influence of growth factors (lack of serum and consequent inability to promote cell cycle exit and increase the proportion of cells in G0); (2) pharmacological cell cycle inhibitors (staurosporine or etoposide); or (3) physiological cell cycle inhibition (excessive contact between neighboring cells). Evaluation of ciliogenesis induction is vitally important for the study of diseases related to ciliary dysfunction, called ciliopathies. That is why the use of correct protocols for inducing cilia formation and an accurate posterior visualization of the cilia after performing said protocols are essential parts in the study of these diseases. To facilitate this task, here we described detailed protocols to induce ciliogenesis in vitro and visualize PC by immunofluorescence microscopy in cultured cells.
