Polarization of T Lymphocytes Is Regulated by Mesenchymal Stem Cells in NZBWF1 and BALB/c Mice
AbstractMesenchymal stem cells (MSCs) have been shown to suppress proliferation andactivation of T lymphocytes in vivo and in vitro although the molecular mechanism of theimmunosuppressive effect is not completely understood. To investigate theimmunoregulatory effects of mice bone marrow mesenchymal stem cells on T lymphocyte,MSCs from NZBWF1 and BALB/c mice were isolated and expanded from bone marrow,and identified with cell morphology and the surface phenotypes. CD3+ T lymphocytesisolated by nylon wool columns were co-cultured with PMA with or without the two strainsof MSCs. Then T cell apoptosis and intercellular cytokines of T cell were assessed by flowcytometry. Quantification of transcription factors T-box (T-bet) and GATA-binding protein3 (GATA-3) expressed in T cells was detected by RT-PCR and western blot. Our resultsshowed that there was a decrease of CD3+ T cell apoptosis when NW MSCs or Bc MSCswere added, and an increase of Th2 subset by NW MSCs and Th1 subset by Bc MSCs wereobserved by co-culturing MSCs with T lymphocytes. It is suggested that, by favoring Th1-cell development and inhibitory Th2-cell development, normal MSCs might interfere withthe SLE development, and that marrow-derived NW MSCs had defectiveimmunoregulatory function when compared with MSCs from healthy mouse strains.
