FIG. 5.

Contraction of 70:30 col/PCL scaffolds with or without 160 μm pores and fibroblasts. Scaffolds were seeded with fibroblasts, and scaffold diameters were measured at varying time intervals to quantify contraction. The same experiment was also performed without seeded fibroblasts. Values represent means and standard deviation for five scaffolds per group, and two independent experiments were performed. Student's t-tests were used to compare the percent change in scaffold contraction of the various groups. *Represents significant difference (p<0.01) relative to 7 day sample of the same group. ^Represents significant difference (p<0.05) compared with scaffolds with fibroblasts for the same time point.
