Fig. 7. HMEC-1 cells treated with DP siRNA eventually form tubes. (A) By 144 hours after cells were transfected with DP siRNA they proceeded to form microvascular tubes. (B) High-magnification view of a microvascular tube from the same set of cells in Fig. 5H that had been treated with DP siRNA shows cells adhered well to one another. Bar, 100 µm (A); 50 µm (B).
