Representative images of vascular islands without an open lumen connection to nearby vessels. A-C) Injected FITC-albumin compared to topical lectin labeling. D-F) Injected FITC-dextran compared to PECAM labeling. For both cases, FITC identified patent vessels (arrowheads), but was absent along vascular islands (arrows). “L” indicates lymphatic vessels. Scale bars = 20 μm.
