Effect of EPCs transplantation on protein expression in different groups. A: Protein expression levels of VEGF, Ang-1 and Ang-2 in different groups. β-actin was used as a protein control to normalize volume of protein expression. B-D: Protein levels were determined by densitometric analysis and normalized to the β-actin signal. Data are expressed as mean ± SD. *Significant difference vs. Sham group (P<0.05); #Significant difference vs. IRI group (P<0.05).
