(A) VEGF concentration in culture medium was significantly greater in the GLP-1 group than in the control group. Data are expressed as means ±SE; n=6, *P<0.05 vs. control. **P<0.01 vs. control. (B) Immunocytochemical examination revealed weakly positive expression of VEGF in control group. (C) Strongly positive expression of VEGF in GLP-1 10 nM group (SP, ×600).
