Colony-formation assay showed curcumin could reverse the proliferation ability of EPCs isolated from diabetic mice. a Representative staining for DiI-Ac-LDL in EPC colonies. Bar, 50 μm. b EPC colonies were counted and analyzed in each group. Number of EPCs presented as mean ± SD (n = 4). EPC endothelial progenitor cell, non-DM nondiabetes group, DM diabetes with saline-treated group, DM + olive oil diabetes with olive oil-treated group, DM + curcumin diabetes with curcumin-treated group (Color figure online)
