Representative lymphatic sprouts labeled for NG2 plus PECAM. Blind-ended endothelial cell segments (arrows), which originate from lymphatic vessels (L) and are structurally similar to blood capillary sprouts are NG2 positive, indicating the presence of vascular pericytes. NG2 labeling does not extend along the upstream lymphatic vessel. Scale bars, 20 μm.
