The migration activity of CD31^-CD146^-SP cells. The migration activity with VEGF-A at a final concentration of 0, 5, 10, and 100 ng/ml. Data are expressed as means ± SD (*, P <0.01) (A). The migration of CD31^-CD146^-SP induced by estrogen (10 μmol/L) (B) and progesterone (30 μmol/L) (C). The minimum concentration of estrogen and progesterone can induce significant migration (P < 0.01). Statistical analysis was performed by the non-paired Student’s t test. The experiments were repeated three times and from three patients’ decidua, but one representative experiment is presented. SP, side population; VEGF-A, vascular endothelial growth factor - A.
