Peptide R1-P2 inhibits FGF2 induced angiogenesis in vitro. (A) Peptide R1-P2 inhibited tube formation in A549 cells were seeded on matrigel layer and treated with FGF2 in the presence or absence of peptide R1-P2. (B) CAM assay showed less vessels formation in peptide R1-P2 treated group. Bar = 100 μm, the error bars indicate the ± SD from three separate experiments, ###P < 0.001, versus control, **P < 0.01, ***P < 0.001, versus FGF2 alone.
