Abstract:

BACKGROUND: Recent development of bioengineering technology and tissue-engineered nerve brings a new hope for the treatment of peripheral nerve injuries, which has gradually become a research spot.
OBJECTIVE: To review the new progress in the repair of peripheral nerve injuries using seed cells, biomaterials and tissue-engineered nerve construction technology.
METHODS: PubMed and CNKI were searched by the first authors for articles concerning nerve tissue engineering and repair of peripheral nerve injuries published prior to July 2013. The keywords were “tissue engineering, peripheral nerves, nerve injuries, stem cells, Schwann cells, scaffold, growth factor” in English and Chinese, respectively. The articles published recently or in the authorized journals were preferred in the same field. Finally, 63 articles were included in result analysis.
RESULTS AND CONCLUSION: Up to now, there is a great advance in the tissue engineering technology for the repair of peripheral nerve injuries. However, most studies are still in experimental step. For the clinical application of nerve tissue engineering, some problems to be solved include: (1) source and ethics of seed cells; (2) immunological rejection following cell proliferation and transplantation; (3) stability and oncogenicity of transplanted cells; (4) degradation rate, optimal porosity, tube thickness and shape; (5) repair timing for in vitro tissue-engineered nerve construction; (6) local release and regulation of various neurobiological factors. With the development of science, many patients with nerve injuries can profit from the solve of these problems.

Key words: peripheral nerves, nerve injuries, stem cells, Schwann cells, biocompatible materials
