Figure 4. Effect of inhibitors on 3D gel contractions.

HUF (left) and HeLa (right) cells were grown in 3D cultures and treated with inhibitors as described. The gels were photographed 24 hrs later and the surface area of the individual gels was quantified. The data represent the mean +SEM. One way ANOVA * = p value < 0.05, *** = p value < 0.001.
