Fig. 1From: Combined effects of interleukin-1β and cyclic stretching on metalloproteinase expression in corneal fibroblasts in vitroThe effects of cyclic stretching on cell morphology are shown. F-actin and nuclei of the cells were stained with rhodamine B and DAPI. a The cells were in the static condition. b–d The cells were exposed to cyclic stretching for 5, 10 and 15 % respectively.
