MiR-21 and FASLG regulated EPCs function in vitro. a CCK-8 analysis of EPCs transfected with FASLG siRNA, miR-21 antagomir and FASLG siRNA, respectively. b In vitro tube formation assay analysis of the angiogenesis ability of EPCs within different groups. c Quantification of tube formation and length in different groups. d CCK-8 were performed to determine the proliferation ability in EPCs co-transfected with miR-21 antagomir and FASLG siRNA. e Tube formation assay were performed to determine angiogenesis within different groups. f Quantification of tube formation and length in different groups. *p < 0.05 vs. negative control. **p < 0.01 vs. negative control
