Figure 3. Figure-3 Induction of corneal fibroblast network by VEGF. The addition of exogenous VEGF (100 ng/ml), significantly increased the number of cell inter-connections in only type 1 cells after 3 h (A) and after 18 h (B). Type 2 fibroblasts do not respond to exogenous VEGF after 3 h (C) and after 18 h (D). The number of tubules formed on Matrigel counted after at 3h and 18h and are presented in E.
