title: Angiogenic monocytes: another colorful blow to endothelial progenitors.
abstract: This Commentary provides perspective on a related article by Sun-Jin Kim and coworkers (Am J Pathol: 172 AJP08-0819), who assess the contribution of bone marrow-derived cells to tumor angiogenesis in a physiologic, non-myeloablative setting and conclude that the actual angiogenic cell type incorporated in the newly formed vessels is actually monocytes/macrophages.
