BACKGROUND: There is a high morbidity after spinal cord injury, and the therapeutic strategy is limited to early surgical intervention, medication and post-treatment exercise that only can improve the motor function slightly. However, there is no effective cure method.OBJECTIVE: To study the effect of partition-type spinal cord catheter combined with bone marrow stromal stem cells on T8 spinal cord transection damage in rats.METHODS: Fifty rats were randomized into five groups (n=10 per group): group I, T8 spinal cord transection (5 mm) was made in rats with no treatment; group II, the partition-type tube was inserted into the injured site after modeling; group III, partition-type tube combined with bone marrow stromal stem cells was implanted into the injured site after modeling; group IV, partition-type tube combined with polyglycolic acid fibers was implanted into the injured site after modeling; group V, partition-type tube combined with bone marrow stromal stem cells and polyglycolic acid fibers was implanted into the injured site after modeling. RESULTS AND CONCLUSION: At 2 and 12 weeks postoperatively, Basso, Beattie and Bresnahan scores were significantly higher in the groups III and IV than the groups I, II, IV (P < 0.05). At 12 weeks postoperatively, the latency of motor evoked potential below the injury plane was significantly decreased in group V compared with groups I, II, III, IV (P < 0.05). Immunohistochemical results displayed that in the groups III and V, regenerated nerve fibers grew positively and arranged orderly among the tubes, and there was no obvious winding phenomenon. Under transmission electron microscopy, a certain number of myelinated nerve fibers were found as bridges among groups. These findings indicate that the partition-type chitosan tube combined with bone marrow stromal stem cells has a good connection with the injured spinal cord a good connection to restore part of electrophysiological properties, accelerate the axon regeneration, recover the motor function, thereby providing a new direction for the treatment of spinal cord injury. 中国组织工程研究杂志出版内容重点：干细胞；骨髓干细胞；造血干细胞；脂肪干细胞；肿瘤干细胞；胚胎干细胞；脐带脐血干细胞；干细胞诱导；干细胞分化；组织工程
