Figure 4.
(A) The Flt23k nanoparticle group showed less total neovascularization compared with the PBS group (P = 0.000) and the blank nanoparticle group (P = 0.019). The Flt23k nanoparticle group showed less graft neovascularization than PBS group (P = 0.009), blank nanoparticle group (P = 0.001), and triamcinolone group (P = 0.000). Error bar is SEM. *P < 0.05, **P < 0.01. (B) The Flt23k nanoparticle group showed less total lymphangiogenesis compared with the PBS group (P = 0.002). The Flt23k nanoparticle group also showed less graft lymphangiogenesis compared with PBS group (P = 0.011) and blank nanoparticle group (P = 0.002). (C) Representative pictures of corneal neovascularization (upper row) and lymphangiogenesis (lower row) in each group.
