Abstract: Bone marrow mesenchymal stem cells (MSCs) are somatic stem cells that can differentiate into progenies of multiple lineages. They play an important role in hematopoiesis and stem cell therapy due to their multi-lineage potentials and immunomodulatory properties. Oxidative stress is a disturbed redox state caused by accumulation of reactive oxygen species. It can induce the senescence and apoptosis of MSCs via phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) and p53 pathways, and inhibit the proliferation and differentiation of MSCs through apurinic/apyrimidinic endonuclease/redox factor 1 (APE/REF-1) and extracellular signal-regulated kinase (ERK) pathways. Furthermore,using anti-stress medication and hypoxic preconditioning, the functions of MSCs can be further enhanced. Accordingly, further studies on the effect of oxidative stress on MSCs and its signaling pathways may be meaningful for the treatment of hematologic diseases and for improving stem cell therapy.

Key words: oxidative stress, mesenchymal stem cells, bone marrow, signaling pathway
