Fig. 3From: Curcumin induces therapeutic angiogenesis in a diabetic mouse hindlimb ischemia model via modulating the function of endothelial progenitor cellsCharacterization of BM-derived EPCs. a Spindle-shaped EPCs could be observed 3 days after plating BM-MNCs. EPCs showed cobblestone-like morphology at day 7. Bar, 200 μm and 50 μm. b EPCs uptaking DiI-Ac-LDL could be visualized (red). Nucleus (blue) was stained by DAPI.
