Abstract:

BACKGROUND: Collagen has been widely used as a medical biomaterial due to its low immunogenicity, good biocompatibility and biodegradability.

OBJECTIVE: To summarize the sources, bioactivity, modification of collagen and its application as a medical biomaterial in recent years.
METHODS: The first author searched related articles in PubMed, Elsevier, Springerlink, and CNKI from 2010 to 2018. The key words were “collagen, crosslinking, immunogenicity, biocompatibility, tissue engineering” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Collagen is mainly extracted from animal tendon, skin, tail and other soft tissues. It has low immunogenicity, good biocompatibility and biodegradability, but has insufficient mechanical strength. Crosslinking modification or combination with other biomaterials can both improve the mechanical properties of collagen. Nowadays, collagen is widely used as hemostatic and wound dressing, biological repair patches, bone repairing materials, drug release carriers and tissue engineering scaffolds, which has a significant role in the clinical repair, regeneration and reconstruction of tissue defects.
