Figure 4. Examples of macrophages nearby lymphatic sprouts during lymphangiogenesis.
A) LYVE-1 positive interstitial cells nearby a LYVE-1 positive lymphatic vessel (L) in cultured rat mesenteric tissues stimulated with VEGF-C. B) LYVE-1/CD11b co-labeling during lymphangiogenesis in the rat mesentery tissue stimulated by chronic inflammation. Cellular extensions from interstitial cells (asterisks) toward the lymphatic vessel support the ability for macrophages to interact with and become lymphatic endothelial cells. Arrowhead identifies a CD11b positive cell along the lymphatic sprout. Scale bars = 50 microns.
