Transplantation of EPCs overexpressing PDGFR-β induces apoptosis of medial cells (VSMCs). Fluorescent TUNEL staining in injured arteries of the a saline control group, b pEGFP-N2-EPCs group, and c pEGFP-N2-PDGFR-β-EPCs group. Arrows indicate TUNEL-positive cells (green). Red: VSMCs stained with SmαA; Blue: nuclei stained with DAPI. d TUNEL-labeling index. **P < 0.01 vs. saline control group; ##P < 0.01 vs. pEGFP-N2-EPCs group (n = 5). L, lumen; M, media. Scale bar = 50 μm
