RFP⁺/GFP⁺ FCs, BMSCs and SU3-RFP cells were cultured in endothelial cell differentiation medium for 24 h, the morphology of the three cell types was observed. The proliferation of fusion cells was faster, and the fusion cells showed elongated protrusions, which connected to form a similar network structure (a). BMSCs were polygonal and fibrillar (b), while SU3-RFP cells showed polymorphism and disorderly growth (c). Scale, 50 μm
