Abstract: Bone marrow microenvironment is a complex network consisting of hematopoietic stem/progenitor cells (HSPCs), nonhematopoietic cells, extracellular matrix and various cytokines. Its components interact to support normal hematopoiesis. Emerging evidence indicates that the dysfunction of mesenchymal stem cells, myeloidderived suppressor cells, cytokines and the epigenetic alterations of HSPCs in the bone marrow microenvironment could influence normal hematopoiesis. Abnormal hematopoiesis contributes to the occurrence of hematological malignancies, such as myelodysplastic syndromes (MDS). Animal models have confirmed that bone marrow microenvironment plays an important role in the original generation and maintenance of malignant diseases of hematopoietic system.

Key words: Myelodysplastic syndromes, Cytokines, Mesenchymal stem cells
