The expression of inflammatory cytokines in pterygium and healthy conjunctival tissues. The expression of 17 inflammatory cytokine genes, including IL-2, IL-4, IL-10, VEGF, IL-1β, TGF-β1, TNF-α, IL-6, MMP2, FGF2, HGF, ICAM-1, IL1-α, MMP9, IL-8, IL-37, and IL-38, was examined with real-time quantitative PCR (q-PCR) in the pterygia (n = 56) and healthy conjunctiva (n = 7). The experiment was repeated three times. The data were presented as the mean ± standard error of the mean (SEM). p < 0.05, conjunctival tissue vs pterygium tissue.
