Increased CCL2 and IL‐8 in the bone marrow microenvironment in acute lymphoblastic leukemia

Abstract

The leukemic BM microenvironment had increased levels of CCL2 and IL-8. These chemokines are known to have suppressive effects in normal hematopoiesis. Our data indicate that CCL2 and IL-8 have a positive impact on BMMSC survival, proliferation, and adhesiveness to ALL cells. Leukemia-associated CCL2 and IL-8 upregulation may represent one possible mechanism of microenvironment perversion in favor of ALL cells.
