A) De novo collagen stained in micro-tissues after five days in culture against soft (0.15 nN/nm) and stiff (1.05 nN/nm) boundaries. B) TGF-β1 increases collagen production per cell equally under soft and stiff boundaries. EGF increases collagen intensity significantly only under soft boundary. Two-way ANOVA, p<0.05: *: Significantly higher than control groups (p<0.05) (n=3). C) Force-per-cell values after four days of culture. EGF does not alter isometric cell force significantly. *: Significantly higher force per cell than all other groups (n=4).
