Abstract: BACKGROUND: Tissue engineering technology relies on biomaterial scaffolds as supporting structures for tissue repair and regeneration. Among these biological scaffolds, electrospun fiber scaffolds have been widely applied in regenerative medicine owing to their mimicry of the natural structure of extracellular matrix.
OBJECTIVE: To summarize the current application of electrospun aligned nanofibers in the field of tissue engineering.
METHODS: Relevant articles included in PubMed from January 2010 to March 2020 were searched by the first author, with key words of “electrospinning; aligned nanofibers; tissue engineering; regenerative medicine; bioactive materials” in English. Relevant articles included in CNKI and Wanfang database from January 2010 to March 2020 were searched with key words of “electrospinning; aligned nanofibers; oriented fiber; tissue engineering; tissue regeneration” in Chinese. Finally, 67 articles were included for review.
RESULTS AND CONCLUSION: Electrospinning is a simple and effective technology for the preparation of nanomaterials. In recent years, many kinds of natural materials or polyester materials with good biocompatibility and biodegradability have been prepared into electrospun nanofiber scaffolds with different structures by electrospinning technology, which are widely used in tissue engineering, regenerative medicine and other fields. Among them, the electrospun oriented nanofiber scaffolds, inspired by the highly directional characteristics of natural extracellular matrix, have highly consistent fiber arrangement direction, which can promote cell adhesion and migration through contact guidance, and the combination with cells or growth factors can further promote cell proliferation and differentiation, and ultimately achieve tissue regeneration in nerve, myocardium, tendon and bone tissue. In the field of regeneration and wound healing, it has great potential and wide application prospect.
