ABSTRACT
OBJECTIVE@#To investigate the effect of acute myeloid leukemia cells in leukemia-microenvironment on proliferation and apoptosis of bone marrow-derived mesenchymal stromal cells (BM-MSC).@*METHODS@#Acute myeloid leukemia (AML) murine models overexpressing MLL-AF9 were established. The number of BM-MSC of wild type (WT) and AML-derived mice were analyzed by flow cytometry. Morphology and growth differences between WT and AML-derived BM-MSC were analyzed by inverted fluorescence microscope. Proliferation and apoptosis of BM-MSC between these two groups were detected by Brdu and Annexin V/PI.@*RESULTS@#Compared with WT-derived BM-MSC, the number and proliferation rate of AML-derived BM-MSC significantly increased (P<0.01, P<0.001), while apoptosis rate decreased (P<0.05). When cultured in vitro, BM-MSC grew faster under conditional medium.@*CONCLUSION@#AML cells can promote proliferation and inhibit apoptosis of BM-MSC.
