Abstract
BACKGROUND Spinal cord injury (SCI) remained one of the challenges to treat due to its complicated mechanisms. Photobiomodulation therapy (PBMT) accelerates neuronal regeneration. Cerium oxide nanoparticles (CeONPs) also eliminate free radicals in the environment. The present study aims to introduce a combined treatment method of making PCL scaffolds as microenvironments, seeded with CeONPs and the PBMT technique for SCI treatment. METHODS The surgical hemi-section was used to induce SCI. Immediately after the SCI induction, the scaffold (Sc) was loaded with CeONPs implanted. PBMT began 30 min after SCI induction and lasted for up to 4 weeks. Fifty-six male rats were randomly divided into seven groups. Glial fibrillary acidic protein (GFAP) (an astrocyte marker), Connexin 43 (Con43) (a member of the gap junction), and gap junctions (GJ) (a marker for the transfer of ions and small molecules) expressions were evaluated. The behavioral evaluation was performed by BBB, Acetone, Von Frey, and radiant heat tests. RESULT The SC + Nano + PBMT group exhibited the most remarkable recovery outcomes. Thermal hyperalgesia responses were mitigated, with the combined approach displaying the most effective relief. Mechanical allodynia and cold allodynia responses were also attenuated by treatments, demonstrating potential pain management benefits. CONCLUSION These findings highlight the potential of PBMT, combined with CeONPs-loaded scaffolds, in promoting functional motor recovery and alleviating pain-related responses following SCI. The study underscores the intricate interplay between various interventions and their cumulative effects, informing future research directions for enhancing neural repair and pain management strategies in SCI contexts.

Abstract
INTRODUCTION Chondroitinase ABC (chABC) is an enzyme could improve regeneration and thereby improving functional recovery of spinal cord injury (SCI) in rodent models. Degradation of the active enzyme and diffusion away from the lesion are the causes of using hydrogels as a scaffold to deliver the chABC into the lesion site. In this meta-analysis, we investigated the effects of chABC embedded in a scaffold or hydrogel on the functional recovery after SCI. METHOD Databases were searched based on keywords related to chABC and spinal cord injury (SCI). Primary and secondary screening was performed to narrow down study objectives and inclusion criteria, and finally the data were included in the meta-analysis. The standard mean difference of the score of the functional recovery that measured by Basso, Beattie, Bresnahan (BBB) test after SCI was used to analyze the results of the reported studies. Subgroup analysis was performed based on SCI model, severity of SCI, transplantation type, and the follow-up time. Quality control of articles was also specified. RESULTS The results showed that embedding chABC within the scaffold increased significantly the efficiency of functional recovery after SCI in animal models (SMD = 1.95; 95% CI 0.71-3.2; p = 0.002) in 9 studies. SCI model, severity of SCI, injury location, transplantation type, and the follow-up time did not affect the overall results and in all cases scaffold effect could not be ignored. However, due to the small number of studies, this result is not conclusive and more studies are needed. CONCLUSION The results could pave the way for the use of chABC embedded in the scaffold for the treatment of SCI and show that this method of administration is superior to chABC injection alone.

Sertoli cell transplantation attenuates microglial activation and inhibits TRPC6 expression in neuropathic pain induced by spinal cord injury. Physiol Behav 2022; 251:113807. [PMID: 35427673 DOI: 10.1016/j.physbeh.2022.113807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 03/10/2022] [Accepted: 04/08/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Cell therapy is a promising treatment method for relieving neuropathic pain caused by spinal cord injuries (SCI). Sertoli cells (SCs) are an attractive choice given their demonstrated secretion of growth factors and immunosuppressant effect. This study mechanistically characterizes the analgesic effect of SCs transplantation. METHODS The clip compression SCI model was carried out on the T12-T13 level in male Wistar rats. One-week post-SCI, SCs were transplanted into the site of injury. Animals underwent Basso, Beattie, and Bresnahan locomotor scoring, mechanical allodynia, and thermal hyperalgesia on a weekly basis for a duration of six weeks. Histological examination of the spinal cord and molecular evaluation of Iba-1, P2Y4, TRPC6, and P-mTOR were performed. SCs survival, measured by anti-Müllerian hormone expression in the spinal cord. RESULTS Animals that received SCs transplantation showed improvement in motor function recovery and pain relief. Furthermore, a cavity was significantly decreased in the transplanted animals (p = 0.0024), the expression level of TRPC6 and caspase3 and the number of activated microglia decreased compared to the SCI animals, and p-mTOR and P2Y4R expression remarkably increased compared to the SCI group. CONCLUSION SCs transplantation produces an analgesic effect which may represent a promising treatment for SCI-induced chronic pain.
