Figure 3. Induction of L-MSC network by VEGF. The addition of different concentrations of exogenous VEGF (0, 1, 10, and 100 ng/ml), on L-MSC seeded on matrigel significantly induced the number of cell-cell interconnections in a dose response manner (A). Comparison of the number of tubules formed on matrigel at different VEGF concentrations is shown in B. Each bar represents the mean±SEM of three independent assays (*p<0.05).
