Lymphatic Endothelial Cell in Endemic Bancroftian Filariasis: A Focus on the Lymphatics of the Tunica Vaginalis Testis

Figure 2

Control group. (a) The PL is thin, with a wavy luminal surface. (b) Monolayer of flat MCs (arrows) without any inflammation below. (c) MCs positive for CK-7. (d) MCs positive for D2-40. (e) Two dilated lymphatics (asterisks) in the submesothelial layer; the valves are clearly seen in the greatest of them (arrows). The transverse diameter (blue line) of the lymphatic is 136.5 μm, and (f) LVs (asterisks) negative for CK-7; no MCs are detected on the free surface ((a), (b) HE; (c), (e) D2-40; and (d), (f) CK-7. Scale bar = 50 μm).
