Caption Transmission electron microscopy of wild type (WT, A-C) and Ramp2tm1Kmca/Ramp2tm1Kmca (RAMP2-/-, D-F) lymph sacs at E14.5. In general, the lymphatic endothelial cells (LECs) of mutant mice appeared significantly thinner than those of wild type littermates. Although obvious edema was present in the interstitial space surrounding both the veins and lymph sacs in mutant embryos, endothelial cells could be followed continuously around both vessel types, without obvious breaks or gaps. Other typical ultrastructural features of lymphatic vessels were identified in both wild type and mutant mice including: overlapping contacts (arrowheads), tight junctions (arrows), and anchoring filaments (A). Occasionally necrotic endothelial cells (**) were observed in mutant mice, but the associated tight junctions remained structurally intact. n=2 wild type and 3 mutants. L, lumen. Scale bar: 1um.
