(A) Ultrastructural image of a zone of a vessel with prominent ECs and a transversally sectioned intravascular pillar (arrow), showing a cover formed by ECs and a core with processes of pericytes (p) and collagen material (col). In the insert, a pillar appears longitudinally sectioned. lu: vessel lumen. (B–K) The appearance and disappearance and the whole-mounted view (B) of three intravascular pillars (arrows) are shown in confocal microscopy. A and insert: Ultrathin sections. Uranyl acetate and lead citrate. (B–K) confocal microscopy, frontal view, 10 µm section, immunofluorescent label with anti-CD34 (green), anti-collagen I (red), DAPI (blue). Bar: (A) 2 µm; (B–K) 20 µm.
