ABSTRACT
Objective To study the difference in immunomodulatory effects among non-Hodgkin lymphoma (NHL)-, Hodgkin lymphoma (HL)- and normal adult bone marrow-derived mesenthymal stem cells (MSCs). Methods MSCs were obtained from HL, NHL and normal adult bone marrow and cultured in expanded medium. Immunophenotype was investigated by FACS. The levels of cytokines were evaluated by enzyme linked immunosorbent assay (ELISA). T-cell suppression ability was evaluated by Transwell. Moreover, the immunoregulatory ability of HL-, NHL- and normal adult bone marrow-derived MSCs was detected by mixed lymphocyte culture assay. Results HL-, NHLand normal adult bone marrow-derived MSCs were similar in morphology and immunophenotype, and they did not express HLA-DR and co-stirnulatory molecules (CD40, CD80 and CD86). All HL-,NHL- and normal adult bone marrow-derived MSCs could significantly suppress T lymphocytes'proliferation in a dose-dependent manner and such an effect could be reversed by anti-TGF-β1 antibody.MSCs differentiated into various mesenchymal lineages did not alter their immunosuppressive effects on T-cell proliferation. Conclusion The similar immunomodulatory effects were found among HL-,NHL- and normal adult bone marrow-derived MSCs, which was not changed by differentiation.
