Biomechanical, Biochemical, and Cell Biological Evaluation of Different Collagen Scaffolds for Tendon Augmentation

Figure 4

Cellular impact on enzymatic degradation after 7 and 21 days of cultivation. Primary human fibroblasts were cultivated on the two different bovine collagen test materials for 7 and 21 days. The stamped product residues were weighed before and after pronase digestion (0.25 U/ml) to determine changes in weight compared to the same material treated with Tris buffer (as positive control). compared between the two materials.
