Fig. 6From: DPSCs treated by TGF-β1 regulate angiogenic sprouting of three-dimensionally co-cultured HUVECs and DPSCs through VEGF-Ang-Tie2 signalingConditioned media from T-DPSCs activated Tie2 signaling. a–c Western blot analysis of the expression of p-Tie2 and VE-Cadherin in HUVECs after treatment with T-DPSC-CM or Ang1 at different time points. Data are mean ± standard error for n = 3 replicates, *p <0.05, **p <0.01Back to article page
