Cytokine secretion evaluated by ELISA. The expressions of TGF-β1 and IL-6 were quantified in various monocultures including islets, STZ-induced islets and rBM-MSCs and cocultures including islets+rBM-MSCs and STZ-induced islets+rBM-MSCs. Data represent the mean±S.E. of values of three independent measurements. Data were analyzed for significant change by using two-way ANOVA and paired t-test (*P<0.05; **P<0.01)
