The effects of cyclic stretching on MMP9 activity in corneal fibroblasts treated with IL-1β. a Zymographic analysis of the conditioned medium treated with IL-1β (0, 0.2, 0.4 or 0.8 ng/mL) for 36 h with or without stretching (5, 10 or 15 %). bd The indicated quantitative data refer to the control and IL-1β groups after cyclic stretching for 36 h and are the mean of three different experiments (n = 6). ND not detected; *p < 0.05, ratio compared to  0.2  ng/mL IL-1β; #p < 0.05, compared with the static control at the same IL-1β treatment
