Wnt3a effect on Lef1 transcription in endothelial cells. (A) Lef1 promoter (B5) activity in EAhy926 cells. Exposure to Wnt3a in side-by-side co-culture activates the Lef1 promoter (*p = 0.0178). (B) Lef1 mRNA levels by quantitative real-time polymerase chain reaction (qRT-PCR) in EAhy926 cells. Wnt3a CM increases the amount of Lef1 mRNA (*p = 0.0379). (C) Lef1 mRNA levels by qRT-PCR in EAhy926 cells overexpressing β-catenin. Wnt3a CM increases the amount of Lef1 mRNA in cells with already activated by β-catenin Wnt signaling (**p = 0.0086).
