Cover picture: Endothelial-monocyte activating polypeptide (EMAP) II has antiangiogenic properties preventing blood vessel ingrowth in two experimental angiogenesis models, and suppresses the growth of primary and metastatic tumors without toxicity in normal organs. These findings are supported through the use of a neovascularization model, the mouse cornea. Basic fibroblast growth factor (bFGF) pellets were implanted into corneal pockets of mice, and the animals received rEMAP II or vehicle. Corneal neovascularization was evident in animals receiving vehicle (top), and was markedly suppressed by treatment with rEMAP II (bottom). Furthermore, EMAP II appears to target growing endothelial cells, and our data suggest that EMAP II is a polypeptide with antiangiogenic properties that targets rapidly growing vascular beds.
