Résumé
BACKGROUND:Stem cells have been shown to not only replace damaged cells, but also secrete trophic factors, bringing a bright future for the treatment of clinical spinal cord injury. OBJECTIVE:To review the latest advances of bone marrow mesenchymal stem cells in animal and clinical research. METHODS:A computer-based search of Kjmed and Wanfang databases was done for relevant articles published from April 2004 to April 2014 using the keywords of“stem cells, spinal cord injuries, embryonic stem cells, neural stem cells, mesenchymal stem cells”in English and Chinese, respectively. RESULTS AND CONCLUSION:Total y 2 745 articles were initial y retrieved, and only 50 articles were included in result analysis. Bone marrow mesenchymal stem cells have become one of the most promising sources of stem cells in the treatment of spinal cord injury. Although the bone marrow mesenchymal stem cellin the treatment of spinal cord injury is stil in its infancy, it has certain effects on the repair of spinal cord injury. The mechanism of action of bone marrow mesenchymal stem cells in the treatment of spinal cord injury is possibly related to the substitution effect, neurotrophic effects, suppression of the immune response and promoting axonal regeneration.
