Evaluation of EPC biological function
. (A) Migration of EPCs cultured with 100 ng/mL SDF-1, n = 9. (B) Proliferation of EPCs cultured with 100 ng/mL VEGF, n = 9. (C) Adhesion test with 100 ng/mL SDF-1, n = 9. (D) Apoptosis test with 100 mg/L TNF-α, n = 9. PPB-control, PPB-EPCs treated with PBS; HPB-control, HPB-EPCs treated with phosphate buffered saline (PBS); UCB-control, UCB-EPCs treated with PBS. * P <0.05; # P <0.01, ** P <0.001; NS, not significant. EPC, endothelial progenitor cells; HPB, peripheral blood from healthy volunteers; PPB, peripheral blood from patients; SDF-1, stromal cell derived factor 1; UBC, umbilical cord blood; VEGF, vascular endothelial growth factor.
