Figure 2From: Ultrastructural characterization of primary cilia in pathologically characterized human glioblastoma multiforme (GBM) tumors Patient #1. GBM cells have an intact primary cilium. Electron micrograph showing a mature primary cilium and basal body with a well-formed cilium-pit (arrow) and endocytotic vesicles (short arrows). Top inset, primary cilia as marked by acetylated tubulin (green) using indirect immunofluorescence analysis. Bottom inset, cross section through the axoneme of another cell. EM scale bar = 100 nm, IIF scale bar = 7 μm.Back to article page
