Abstract

Abstract

Objective To achieve the purpose of promoting movement function of the injury nerve by using the joint therapy of NT-3-HUMSCs and SOCS3 gene silencing on SD rats' spinal cord injury. Methods (1) We used adherence method in vitro human umbilical cord-derived mesenchymal cells ( HUMSC) during separation, purification and identification. (2) Then constructed NT-3 gene eukaryotic expression vector, which was transfected into its HUMSC, and constructed NT-3-HUMSC cell survival in vitro assay conditions and NT-3 expression. (3) We selected specific targets for SOCS3 screening and for sequence homology analysis.A negative control group was established. siRNA was designed and synthesized in vitro detection. (4) SD rats with spinal cord injury model were divided into two categories: (1) sham group with 10 rats; (2) T12 whole spinal cord injury model with 40 rats. The 40 rats were randomly divided into four groups with 10 rats in each group (saline treatment group, siRNA + NT-3-HUMSCs treatment group, NT-3-HUMSCs treatment group and siRNA treated group) . Motor function of the rats were evaluated respectively in 1, 2 and 3 months after the modeling was established successfully.Results (1) siRNA + NT-3-HUMSCs treatment group's BBB scores was significantly higher than NT-3-HUMSCs, SOCS3-siRNA and physiological saline groups (P <0.05) . (2) The grid climbing experiments showed that the neural functional recovery performed better in siRNA + the NT-3-HUMSCs treatment group compared to the NT-3-HUMSCs, SOCS3-siRNA and physiological saline groups (P <0.05) . Conclusion The NT-3-HUMSCs joint SOCS3 gene silencing in the treatment of SD rat spinal cord injury can improve the motor function of SD rat spinal cord injury.
