Diabetes impairs MT expression and function of EPC in patients. EPCs were collected from peripheral blood of healthy control subjects and patients with diabetes. The expression of MT was detected by Western blot, with β-actin used as loading control (A). The apoptosis was analyzed by flow cytometry using annexin V/PI staining (B). The angiogenic function was evaluated by tube formation assay (C). Data are mean ± SD. n = 6/group. *P < 0.05 vs. healthy subject EPCs (Health-EPC).
