The expression of p-Tie2 and p-VEGFR2 in HUVECs. a–c Western blot analysis of the expression of p-Tie2 and Tie2 in HUVEC/T-DPSC co-culture with or without high concentration Ang2 (1000 ng/mL) for 24 h. d, e HUVECs were pretreated with the Tie2 inhibitor (5 μM) for 12h, then treated with T-DPSC-CM or Ang1 for 30 min. Western blot analysis of the expression of p-Tie2 in HUVECs. f, g HUVECs were pretreated with the VEGFR2 inhibitor (5 μM) for 12h, then treated with VEGF for 2, 5, and 10 min. Western blot analysis of the expression of p-VEGFR2 in HUVECs. Data are mean ± standard error for n = 3 replicates, *p <0.05, **p <0.01, ***p <0.001, ****p <0.0001
