neoplasm
• after tamoxifen-induced recombination to ablate Vegfa in cultured bone marrow-derived macrophages, the BMDMs are unable to promote trans-endothelial migration of tumor cells or enhance permeability of the endothelial monolayer, both important for metastasis
• adoptive transfer of Vegfa-null monocytes infiltrate lung metastases comparably to wild-type inflammatory monocytes
