Abstract: BACKGROUND: Collagen is one of the widely used scaffold materials in tissue engineering, but commercial collagen is mainly derived from pigskin, cowhide, and other mammals, and there are some zoonotic diseases risks, and religious restrictions. Nowadays, fish skin collagen biomaterials with many functional properties without disease or religious restrictions have become a research hotspot in tissue engineering.
OBJECTIVE: To review the extraction, functional modification of fish skin collagen, and its research progress, and main applications in tissue engineering.
METHODS: The first author retrieved the literature related to tissue engineering and fish skin collagen included in PubMed, CNKI, Wanfang, and other databases from 2005 to 2020 and selected articles in highly relevant and authoritative journals. The English and Chinese search terms were “fish skin collagen; tissue engineering”.
RESULTS AND CONCLUSION: Fish skin collagen has good physical and chemical properties, mechanical strength, and biocompatibility. It is expected to replace mammalian collagen and has attracted the attention of biomedical researchers. It is widely used in various tissue engineering, such as skin wound healing, bone and cartilage tissue engineering, blood vessel and nerve regeneration. However, there are many problems in transforming basic research into clinical application, such as: which extraction method is more fast and efficient for fish skin collagen factory production; and which functional modification scheme for fish skin collagen to achieve composite construction of grafts; the standard of how to improve the mechanical properties and degradation properties of fish skin collagen-based materials to support the regeneration and repair of bone and cartilage tissue; how to construct scaffold materials to improve the perfect and rapid repair of skin trauma.

Key words: fish skin collagen, tissue engineering, extraction, modification, bone tissue engineering, cartilage tissue engineering, skin tissue engineering, biomedical applications
