Where tumor cells boldly go: Weill Cornell cancer biologists shed light on the metastatic niche
NEW YORK (May 1, 2009) -- Traditionally, cancer biologists
have embraced a simple and direct model of the disease process: The tumor -- the "seed" -- was seen as bearing total responsibility for the spread of cancer to distant tissues -- the "soil" in which the seed embedded itself, grew, and repr...
