Abstract excerpt
The balance between proangiogenic Angiopoietin-1 (Ang-1) and the antagonistic Ang-2 is important both for leukemogenesis and chemosensitivity in human acute myelogenous leukemia (AML). We examined the release of Ang-1 and Ang-2 by AML cells cultured alone and in cocultures with stromal cells. Detectable Ang-1 release from AML cells was observed for most patients (62/91), whereas Ang-2 release was detected only...
