    • Abstract:
      Study design:Transplanted primates' neural stem cells (NSCs) tissue engineering complex into spinal cord injury (SCI) model rats, analyze and evaluate the long-term effects of repairing.Objectives:Primate NSCs were cultured in self-assembling peptide nanofiber scaffolds to repair SCI.Setting:Sun Yat-sen Memorial Hospital, Guangzhou, China.Methods:Primate NSCs were isolated and cultured in self-assembling peptide nanofiber scaffolds. T10 SCI model was established; the rats were randomly divided into four groups: NSC plus self-assembling peptide scaffold group; NSC group; self-assembling peptide scaffold group; and control group. Immunohistochemical staining and electronic microscope were used to investigate the growth and differentiation of transplanted NSCs. The motor function of the hind limbs of rats was evaluated (P<0.05 was considered as statistically significant).Results:NSCs and NSCs cultured in self-assembling peptide nanofiber scaffolds could be induced to differentiation into neurons, glial cells and oligodendrocytes in vitro. The primate NSC culture was established in self-assembling peptide scaffolds. No significant difference was seen in the differentiation rate between primate NSCs cultured in self-assembling peptide nanofiber scaffolds and primate NSCs cultured in regular medium. The motor function of the hind limbs in the NSC plus self-assembling peptide scaffold group was significantly better than that of the other three groups. In addition, the NSCs of the NSC group mainly differentiated into astrocytes.Conclusion:Transplantation of primate NSCs cultured in self-assembling peptide scaffolds is efficient for repairing the injured spinal cord and for improving the motor function of spinal cord in rats.Sponsorship:The National Natural Science Foundation of China; Science and Technology Office of Guangdong Province.
