"A new study finds that a group of little-explored cells in the tumor microenvironment likely serve as important gatekeepers against cancer progression and metastasis. Published in the January 17 issue of Cancer Cell, these findings suggest that anti-angiogenic therapies &amp;amp;#150; which shrink cancer by cutting off tumors' blood supply &amp;amp;#150; may inadvertently be making tumors more aggressive and likely to spread."^^<http://www.w3.org/2001/XMLSchema#string>
