Diversity of cilia tip morphology in human islet cells. (A–C) Demembranation reveals a conserved central microtubule organization where the microtubule filaments coalesce and terminate at a dense tip complex. The number of microtubules present at the tip is usually between 3 and 5. (D and F) Unextracted samples with intact ciliary membrane show greater heterogeneity including ciliary bulbs and bulges. Scale, A–C, 300 nm; D–F, 400 nm.
