Cord Injury

Spinal Cord Injury (SCI) causes irreversible functional loss of the affected population. The incidence of SCI keeps increasing, resulting in huge burden on the society. The pathogenesis of SCI involves neuron death and exotic reaction, which could impede neuron regeneration. In clinic, the limited regenerative capacity of endogenous cells after SCI is a major problem. Recent studies have demonstrated that a variety of stem cells such as induced Pluripotent Stem Cells (iPSCs), Embryonic Stem Cells (ESCs), Mesenchymal Stem Cells (MSCs) and Neural Progenitor Cells (NPCs) /Neural Stem Cells (NSCs) have therapeutic potential for SCI. However, the efficacy and safety of these stem cellbased therapy for SCI remain controversial. In this review, we introduce the pathogenesis of SCI, summarize the current status of the application of these stem cells in SCI repair, and discuss possible mechanisms responsible for functional recovery of SCI after stem cell transplantation. Finally, we highlight several areas for further exploitation of stem cells as a promising regenerative therapy of SCI.

Background: Spinal cord injury (SCI) is relatively common in dogs and is a devastating condition involving loss of sensory neurons and motor  neurons. However, the main clinical protocol for the management of SCI is surgery to decompress and stabilize the vertebra. Cell transplantation therapy is a very promising strategy for the treatment of chronic SCI, but extensive preclinical and clinical research work remains.Aim: The aim of this study is to confirm the effect of bone marrow-derived mononuclear cell (BM-MNC) transplantation for chronic SCI in dogs.Methods: We tested the treatment efficiency of chronic SCI in 12 dogs using BM-MNC transplantation. Neurological evaluation used the Texas Spinal Cord Injury Scale (TSCIS). Concurrently, we characterized the transplanted cells by evaluation using quantitative real-time polymerase chain reaction, flow cytometry, and enzyme-linked immunosorbent assay.Result: All dogs had a pre-transplantation TSCIS score of 0. Two animals did not show any improvement in their final TSCIS scores. The remaining 10 dogs (83.4%) achieved improvement in the final TSCIS scores. Five of them (41.7%) regained ambulatory function with a TSCIS score greater than 10. We determined that canine BM-MNCs expressed hepatocyte growth factor (HGF) mRNA at higher levels than other cytokines, with significant  increases in HGF levels in cerebrospinal fluid within 48 hours after autologous BM-MNC transplantation into the subarachnoid space of the spinal dura matter in dogs.Conclusions: BM-MNC transplantation may be effective for at least some cases of chronic SCI.

Objectives:Traumatic spinal cord injury (tSCI) remains a major clinical challenge. Cell transplantation brings a glimmer of light, among them olfactory ensheathing cells (OECs) have shown some neurorestorative effect. Due to the results of each group lack basic consistency, many technical details are believed to affect the overall outcome. We compare the clinical outcome of intramedullary transplant of olfactory ensheathing cells for patients with spinal cord injury at multi-centers worldwide, and to explore the potential standardized transplantation that suits for the clinical requirements.Methods:Here, we used the Pubmed and CNKI databases to search online the literatures published in the last 20 years for the clinical studies/trials of OECs for chronic spinal cord injury in the representative clinical center. The results of these representative clinical treatment centers were searched and analyzed. The parameters which may affect the effect including the concentration of cells, the total number of cells, the choice of incision, the site of transplantation, the number of transplantation sites, the advantages and disadvantages of transplantation equipment, and postoperative management, were compared carefully to clarify its impact on the clinical results.Results:In these literatures, 2 Chinese centers, 1 Australian center and 1 European center were selected for intraspinal transplantation. The reason of different results may be due to the excessive injection times and/or the excessive total injection volume.Conclusions:Cell implant to the spinal cord parenchyma is effective for restoring neurological functions, but improper procedures may lead to ineffective results. Concise surgery appears to be more suitable for clinical application than ostensibly precise and complex injection procedures. Sufficient rehabilitation training is surely necessary for the integration of motor recovery after cell transplantation.
