mRAN expression profiles in bone marrow mesenchymal stem cells (MSC) from Wild Type and Lama4-deficient mice co-cultured with MLL-AF9 AML cells

Bone marrow (BM) niche contributes to hematopoietic regeneration and can be remodeled by leukemic cells. We have found that Lama4 deletion in mouse mesenchymal stem cells (MSCs) could promote the proliferation of MLL-AF9 acute myeloid leukemia (AML) cells and chemoresistance of the cells to chemotherapy cytarabine. However, whether Lama4 deficient MSCs are more susseptible for AML cell remodeling remains to be explored. Here we report that differential molecular alterations in Lama4 deficient MSCs compared to wild type MSCs after being exposed to the AML cells for 48hours, which might be related to the enhanced AML cell proliferation and chemoresistance.
