Mesenchymal stem cells (MSCs) have are multipotent stem cells that can differentiate into a variety of cell types and contribute to regeneration of mesenchymal tissues. It is important for an organism to expand and maintain quantity and quality of MSCs with the advance of age. Therefore, it needs to address senescence-associated changes in metabolism of MSCs. In order to investigate cellular senescence, we used the cellular aging model of stress-induced premature senescence (SIPS) in human bone marrow-derived MSCs (hBM-MSCs) by treatment of sublethal dose of H2O2. Cellular senescence by oxidative stress was confirmed by various analysis, including WST-8 assay and cell cycle analysis in control and oxidative conditions (150 μM H2O2). In this study, proton (1H) nuclear magnetic resonance spectroscopy (NMR) was used to elucidate the difference of metabolites in control and hMSCs treated with H2O2. Among those metabolites, choline and leucine were identified as up-regulated metabolites and glycine and proline were identified as down-regulated metabolites by 1H-NMR. The results suggest that metabolomics approach provide senescence marker to study the effects of cellular senescence on cell metabolism.
