Tumors must establish new vascular network to promote growth and metastasis. The dependency of tumors on angiogenesis provides a rationale for anti-angiogenesis therapy of cancer targeted at shutting down the tumor blood-supply. Endothelial progenitor cells (EPCs) are precursors to vascular endothelial cells originating from the bone marrow, which have the ability to form endothelial colonies in vitro, may integrate into the neovasculature of tumors and could promote tumor angiogenesis.EPCs have been detected in the circulation of lymphoma-bearing mice and patients with cancer.
