Figure 5. uPA mRNA in cultured normal conjunctival and pterygium fibroblasts of various stages measured by quantitative real-time PCR. Comparison of uPA mRNA levels between normal conjunctiva and pterygium fibroblasts at various stages. Data are given as mean±SD (n=5). *Significant difference (p<0.05) compared with normal. #Significant difference (p<0.05) compared with stage I. &Significant difference (p<0.05) compared with stage II.
