C-peptide levels (ng/mL) after 1 h of NCD treatment. C-peptide levels were measured at 5.5 and at 16.5 mM glucose. The results are presented as means ± SD. *Significant difference between all islet groups versus control islets; ^#significant difference between all islet groups versus STZ-treated islets; ^##significant difference between islets treated with NCD before STZ versus islets treated with NCD after STZ.
