Abstract

Collagen based scaffolds are widely used for tissue engineering strategies; many are designed to biodegrade gradually and become populated with host cells. The effect of infiltration by host cells on the mechanical properties of the scaffolds is unclear. We have used fibroblast populated collagen lattices to study the effects of the presence of 3T3 mouse fibroblasts on the mechanical properties of collagen gels containing glycosaminoglycans (GAGs) crosslinked with the carbodiimide, 1,1-carbonyldiimidazole (CDI), and the polyamine, putrescine (Put).
