Objective To observe the influence of the bone marrow microenvironment of normal or acute lymphoblastic leukemia on biological characteristics of Jurkat cells. Methods We collected the Jurkat cells which had been co-cultured with bone marrow stromal cells from 6 cases of acute lymphoblastic leukemia
2 cases of iron deficiency anemia
or 2 cases of idiopathic thrombocytopenic purpura for 10 d
and then observe the changes of Jurkat cells’ proliferation
cell cycle
apoptosis
differentiation and daunorubicin (DNR) intake dose. Results Leukemia bone marrow stromal cells promoted Jurkat cells’ adhesion
chemotaxis and reduction of intake dose than normal bone marrow stromal cells; but were weaker in inhibition of proliferation and promotion of differentiation. Leukemia bone marrow stromal cells inhibited Jurkat cells’ apoptosis
and the normal bone marrow stromal cells promoted apoptosis. Conclusion The micro-environment of normal bone marrow stromal cells promote the apoptosis and differentiation
and inhibit the proliferation of Jurkat cells
in comparison with leukemia bone marrow stromal cells
and increase Jurkat cells’ sensitivity to the DNR.
