Down-regulation of CXCR7/ERK signaling decreased the CAD-derived EPCs functions in vitro. a: Quantitative analysis and typical images for EPCs migration (**P < 0.01 vs. normal EPCs; n = 3 in each group). b: Quantitative analysis and typical images for EPCs adhesion (**P < 0.01 vs. normal EPCs; n = 3 in each group). c: Quantitative analysis and typical images for the complete tube formation in EPCs (**P < 0.01 vs. normal EPCs; n = 3 in each group). d: Typical images and quantitative analysis on the protein levels of CXCR7 and p-ERK in cultured EPCs measured by Western Blotting (**P < 0.01 vs. normal EPCs; n = 3 in each group)
