摘要

Mesenchymal stem cells (MSCs) are multipotent cells showing potential for use in regenerative medicine. Culture techniques that are more stable and methods for the more efficient production of MSCs with therapeutic efficacy are needed. We evaluate the effects of growing bone marrow (Bm)-derived MSCs in the presence of L-carnitine, which is believed to promote lipid metabolism and to suppress apoptosis. The presence of L-carnitine decreased the degree of drug-induced apoptosis and suppressed adipogenic differentiation. Metabolomic analysis by means of the exhaustive investigation of metabolic products showed that, in addition to increased beta-oxidation and the expression of all carnitine derivatives other than deoxycarnitine (an intermediate in carnitine synthesis), polysaturated and polyunsaturated acids were down-regulated. An integrated analysis incorporating both serial analysis of gene expression and metabolomics revealed increases in cell survival, suggesting the utility of carnitine. The addition of carnitine elevated the oxygen consumption rate by BmMSCs that had been cultured for only a few generations and those that had become senescent following repeated replication indicating that mitochondrial activation occurred. Our exhaustive analysis of the effects of various carnitine metabolites thus suggests that the addition of L-carnitine to BmMSCs during expansion enables efficient cell production.
