Extended Data Fig. 3. Intercellular junctions of lymphatic endothelial cells of the nasopharyngeal lymphatic plexus.

Extended Data Fig. 3

a,b, Immunofluorescence images of whole mounts of the dorsal and ventral portions of nasopharyngeal lymphatic plexus (NPLP) stained for VE-cadherin (VE-cad) and LYVE1 in adult (8–10 weeks old) Prox1-GFP mice. White and yellow dashed-line box areas are enlarged in the centre and right panels. Blood capillaries are highlighted in pink. Zipper-like intercellular junction (magenta arrowheads) predominated (95%) in lymphatics with little or no LYVE1 staining, whereas button-like intercellular junctions (blue arrowheads) were more numerous (21%) in LYVE1+ lymphatics. Scale bars, 100 μm. Similar findings were obtained from n = 4 mice in two independent experiments. Bars indicate mean ± s.e.m. P values for junctions in LYVE1- and LYVE1+ lymphatics were calculated by two-way ANOVA test followed by two-tailed Holm-Sidak’s multiple comparison post-hoc test.
