Cell proliferation ability assay. A: Representative BrdU incorporation in primary cultured human limbal epithelial cells treated with siRNA-F, siRNA-p57, and siRNA-p15 with or without TGF-β1 or TGF-β2 treatment (1 ng/ml). B: MTT assay showing effects of siRNA-F, siRNA-p57, and siRNA-on cell proliferation of TGF-β1 or TGF-β2 treatment (1 ng/ml) in primary cultured human limbal epithelial cells. In the image, NS indicates not significant, the asterisk indicates a p<0.05, and the double asterisk indicates a p<0.01.
