title: Tumor-associated fibroblasts as "Trojan Horse" mediators of resistance to anti-VEGF therapy.
abstract: While targeting VEGF has shown success against a number of human cancers, drug resistance has resulted in compromised clinical benefits. In this issue of Cancer Cell, Crawford et al. (2009) report that tumors resistant to anti-VEGF therapy stimulate tumor-associated fibroblasts to express proangiogenic PDGF-C, implicating it as a potential therapeutic target.
