ABSTRACT

BACKGROUND:

To summarize the progress of tissue engineering in repairing spinal cord injury in recent years.DATA SOURCES A computer-based online search of PubMed database (http//www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed for articles published between September 1999 and September 2009 with the key words of "spinal cord injury, tissue engineering" in English and Chinese, respectively. Articles published recently or in authoritative journals in the same field were selected.DATA SELECTION Inclusion criteria clinical or experimental study about tissue engineering in repairing spinal cord injury.Repetitive studies were excluded. A total of 29 articles were included.MAIN OUTCOME

MEASURES:

Seed cell selection of tissue engineering; requirements of scaffold materials of tissue-engineered spinal cord, neurotrophic factor for regeneration, special internal environment construction for regeneration.

RESULTS:

Seed cells of tissue-engineered spinal cord include Schwann cells, olfactory ensheathing cells, embryonic stem cells, neural stem cells and bone marrow stromal stem cells. Scaffold materials involve synthetic or modified natural materials, such as polyglycolic acid, polylactic acid, and lactic acid/glycolic acid copolymer, which benefit cell attachment and nutrition factor aggregation following surface modification. Antibodies that promote or inhibit nerve growth factor in combination with polyoxyl are coupled to function as tissue-engineered scaffold, which may be approaches to repair spinal cord injury by tissue engineering in combination with stem cell transplantation and electric field/magnetic field stimulation.

CONCLUSION:

The optimal elements for tissue engineering are the key role in repairing spinal cord injury by tissue engineering.
