Figure 2From: Role of prostaglandin E receptor subtypes EP2 and EP4 in autocrine and paracrine functions of vascular endothelial growth factor in the inner earVEGF protein levels in the inner ear measured by ELISA. (A) VEGF protein levels in samples treated with 0.01 or 0.1 mg/ml EP2 agonist were significantly higher than those in samples treated with physiological saline (**, p < 0.01, and ***, p < 0.001, ANOVA with Scheffe's method). (B) VEGF protein levels in samples treated with 0.01 or 0.1 mg/ml EP4 agonist were significantly higher than those in samples treated with 0.01 or 0.1% DMSO, respectively (*, p < 0.05, **, p < 0.01, Student's t-test).Back to article page
