 Context examples 

NRP1 is a membrane-bound co-receptor normally expressed by endothelial cells and overexpressed by certain tumor cells, and plays a role in angiogenesis, cell survival, migration, and invasion.

(Anti-Neuropilin-1 Monoclonal Antibody MNRP1685A, NCI Thesaurus)

Anti-EGFL7 monoclonal antibody MEGF0444A binds to EGFL7, thereby preventing the activities of EGFL7 on endothelial cells and inhibiting the survival and migration of endothelial cells during angiogenesis.

By blocking the interaction of SEMA4D and PLXNB1, VX15/2503 may cause an inhibition of endothelial cell activation and migration, eventually leading to an inhibition of angiogenesis and tumor cell proliferation.

(Anti-SEMA4D Monoclonal Antibody VX15/2503, NCI Thesaurus)

Apatinib selectively binds to and inhibits vascular endothelial growth factor receptor 2, which may inhibit VEGF-stimulated endothelial cell migration and proliferation and decrease tumor microvessel density.

(Apatinib, NCI Thesaurus)

It is involved in both adhesion and migration of cells.

(APC Gene, NCI Thesaurus)

ALK-1, a member of the transforming growth factor beta (TGF-b) type I receptor family, is overexpressed on endothelial cells in a variety of tumor cell types and increases endothelial cell proliferation and migration.
