In this review, we recapitulate the molecular mechanisms involved in this angiogenic switch. The rat osteosarcoma model employed would permit further studies in the sequential events leading to initial recruitment of blood vessels and could lead to development of an angiogenesis-based panel of circulating blood cells (endothelial cells, endothelial progenitor cells and accessory cells) that can be quantified and used to detect microscopic tumors or to follow the efficacy of antiangiogenic therapy. Such a result would lead to the possibility of early therapy in cancer progression. Copyright© 2007 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved
