Fig. 3From: Combined effects of interleukin-1β and cyclic stretching on metalloproteinase expression in corneal fibroblasts in vitroThe effects of cyclic stretching and IL-1β on MMP2 activity in corneal fibroblasts. MMP2 was detected by western blot (a) and quantified by densitometry (b–d). The indicated quantitative data are the mean of three different experiments (n = 6). *p < 0.05, ratio compared to 0 ng/mL IL-1β; #p < 0.05, compared with the static control at the same IL-1β treatmentBack to article page
