A novel hydrogel for biomedical applications was successfully fabricated by human-like collagen (HLC) and carboxymethylcellulose (CMC) with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) and adipic acid dihydrazide (ADH) as cross-linkers. The interior morphologies of these hydrogels were also characterized before and after degradation by collagenase I and simulated body fluid (SBF). The results of in vitro degradability tests of these hydrogels that the CMC-HLC/EDC-ADH hydrogel in SBF indicated that possesses slow degradability than in collagenase I in vitro. Therefore, the results provided the possibility that CMC-HLC/EDC-ADH hydrogels are suitable for biomedical applications such as soft tissue augmentation for their good biocompatibility.
