Lymphatic vessels constitute a specialized vasculature that is involved in development, cancer, obesity, and immune regulation. The migration of lymphatic endothelial cells (LECs) is critical for vessel growth (lymphangiogenesis) and vessel remodeling, processes that modify the lymphatic network in response to developmental or pathological demands. Using the publicly accessible results of our genome-wide siRNA screen, we characterized the migratome of primary human LECs and identified individual genes and signaling pathways that regulate LEC migration. We compared our data set with mRNA differential expression data from endothelial and stromal cells derived from two in vivo models of lymphat..
