blood vessel growth into the angioreactors implanted in mice. Mecha-nistic studies show that CYLD regulates angiogenesis by mediating the spreading and migration of vascular endothelial cells. Silencing of CYLD dramatically de-creases microtubule dynamics in endo-thelial cells and inhibits endothelial

Abstract. Angiostatin, a circulating inhibitor of angiogenesis, was identified by its ability to maintain dormancy of established metastases in vivo. In vitro, angiostatin inhibits endothelial cell migration, proliferation, and tube formation, and induces apoptosis in a cell type–specific manner

Although the migration rate was two times lower in the microfluidic assay than in the conventional assay, an identical 1.5-times

Abstract. The serine/threonine p21-activated kinase (PAK) is an effector for Rac and Cdc42, but its role in regulating cytoskeletal organization has been controversial. To address this issue, we investigated the role of PAK in migration of microvascular endothelial cells. We found that a dominant
