**Figure 3. **The effect of Y-27632 on fibroblast contractility.

**A**: TGFβ1 induced collagen contraction over time. Y-27632-application significantly inhibited the contraction of fibroblast-seeded
collagen gels.

**B**: Statistical analysis of the area of collagen gels by

ImageJ software. Values are means±SEM (n=3). *p<0.01 (Student’s

*t*-test).
