LTα1β2 induces the formation of complex lymphatic networks. In vitro analysis of the effect of LTα1β2 stimulation on lymphatic endothelial cell tube formation assay showing (A) total branching length, (B) segment length (pixels), (C) number of nodes, and (D) number of meshes. (E) Representative photomicrographs of nontreated, FCS-treated, and LTα1β2-treated lymphatic endothelial cells. Data are representative of three independent experiments. *p < 0.05 after one-way repeated measurements ANOVA analysis.
