Collagen-based scaffolds enriched with glycosaminoglycans isolated from skin of Salmo salar fish

The results showed that the addition of glycosaminoglycans improves the properties of collagen-based scaffolds. Mechanical strength was increased by GAGs addition as well as the porosity of studied materials. Each scaffold with and without GAGs displayed porous structure with interconnected regular shaped pores. The attachment of cells was better for pure collagen scaffold, however, GAGs additive promoted the cells proliferation on the scaffold.
