Profibrotic activation was induced by TGF-β1 in primary cultured human pterygium fibroblasts and the effect of rosiglitazone treatment on α-smooth muscle actin (α-SMA), and extra cellular matrix proteins synthesis was detected by western blotting, real-time PCR, immunostaining, and flow cytometry.
The objective of the present study was to investigate the association between TGF-β1 gene expression and pterygium in atopic and nonatopic participants.
Fibroblasts and epithelial cells from primary pterygium and normal human conjunctiva were cultured in medium with or without transforming growth factor beta1 for up to 3 days. c-Myc protein expression was analysed by indirect immunofluorescence.
