Antiangiogenic drugs have been used as anticancer agents to target tumor endothelial cells or pericytes. Because of limited efficacy of the current monotherapies, there is a strong demand for the dual targeting of endothelial cells and pericytes. Here, we identify Olfactomedin-like 3 (Olfml3) as a novel proangiogenic cue within the tumor microenvironment. Tumor-derived Olfml3 is produced by bot...
