Reduced KLF2 level of MSC from DM bone marrow was restored by oxytocin. (A) KLF2 mRNA was assessed in DM-MSC treated with various concentrations oxytocin (n=3). (B) KLF2 mRNA was analyzed in MSC from non-DM or DM bone marrow treated with PBS or oxytocin for 24 hours (n=3). (C) The level of KLF2 protein was reduced in DM-MSC, whereas restored by oxytocin (n=3). (D) Oxytocin-induced KLF2 mRNA was assessed in DM-MSC transfected with scrambled siRNA or KLF2 siRNA (n=3). (E) After transfection with KLF2 plasmid for 24 hours, 293T cells were treated with PBS or oxytocin for 24 hours. KLF2 protein level was examined by Western blot (n=3). Quantification analysis was performed and data in the graph represented the mean ± standard deviation.
