Project description:Human iPSC-derived thoracic spinal cord organoids were transplanted into spinal cord injury mice, and spinal cord tissue was collected after 7 weeks. The transplantation resulted in functional recovery and neural circuit remodeling in the injured mice.

Project description:The goal of this study is to elucidate the influence of hemisection injury at thoracic spinal cord (T9) and epidural electrical spinal stimulation (L2-S1) on transcriptome of injured thoracic spinal cord. mRNA profiles of spinal cord at 5 days-post injury with or without epidural electrical spinal stimulation (L2-S1) and before injury were generated. Our study represents the detailed analysis of transcriptomes of injured spinal cord with biologic replicates, generated by RNA-seq technology.

Project description:We profiled spinal cord tissue at the site of a moderate contusion injury at the level of the thoracic spinal cord We examined several timepoints following injury, including sham and days 1,3 and 7 following injury and compared differential expression of genes within a genotype and across genotypes (trkB.T1KO/trkB.T1WT) at each timepoint. Tissue was profiled at baseline (sham) condition and then 1, 3 and 7 days after thoracic moderate contusion injury

Project description:After spinal cord injury, fibrotic scars will form, which affect tissue regeneration and functional recovery in the body. However, the differences in fibrotic scars produced by different segments of the spinal cord are still unclear. Here, we demonstrate that after the same spinal cord hemisection injury, the thoracic spinal cord produces the most scars, while the lumbar and cervical spinal cords have fewer scars, and there are also significant differences in functional recovery after injury in the three segments. By comparing the differences in fibrosis scars produced by cervical spinal cord, thoracic spinal cord, and lumbar spinal cord, as well as the different abilities of fibroblasts to promote fibrosis in vitro, the potential mechanism characteristics of injury repair in different segments of the spinal cord were revealed. This article explores the impact of spinal cord segment differences on fibrosis scar formation and their relationship with behavioral functional recovery, revealing the regional heterogeneity of spinal cord tissue fibrosis scar formation and deepening our understanding of the complexity of CNS scar formation. This provides new ideas for future targeted treatment to improve functional recovery after specific spinal cord injuries.

Project description:Excerpt from a larger study which characterized the transcriptional effects of a spinal cord contusion injury in rats. This is the data from the almost chronic contusion state (35 days) at the injury site (Thoracic 8) - where we saw significant changes in several areas, including cholesterol metabolism genes. Other spinal cord areas (rostral, caudal) and time-points (3 hours, 24 hours, 7 days and 35 days) were analyzed as well and are discussed in our paper and at www.crpf.org/microarray. Keywords = Spinal Cord Injury Keywords = chronic Keywords = thoracic Keywords = cholesterol Keywords: repeat sample

Project description:The aneurysm clip impact-compression model of spinal cord injury (SCI) in animals mimics the primary mechanism of SCI in human, i.e. acute impact and persisting compression; and its histo-pathological and behavioural outcomes are extensively similar to the human SCI. In order to understand the distinct molecular events underlying this injury model, an analysis of global gene expression of the acute, subacute and chronic stages of a moderate to severe injury to the rat spinal cord was conducted using a microarray gene chip approach. Rat thoracic spinal cord (T7) was injured using aneurysm clip impact-compression injury model and the epicenter area of injured spinal cord was isolated for RNA extraction and processing and hybridization on Affymetrix GeneChip arrays.

Project description:The goal of this study is to elucidate the influence of hemisection injury at thoracic spinal cord (T9) on the transcriptome of the lower lumbar spinal cord at acute phase. mRNA profiles of spinal cord at 4 days-post injury and before injury were generated. 72 Differentially Expressed Genes (DEGs) were observed. Our study represents the detailed analysis of transcriptomes of spinal cord distal to the hemisected lesion at acute phase, with biologic replicates, generated by RNA-seq technology.

Project description:We analyzed the changes in the spinal cord transcriptome after a spinal cord contusion injury and MSC or OEC transplantation. The cells were injected immediately or 7 days after the injury. The mRNA of the spinal cord injured segment was extracted and analyzed by microarray at 2 and 7 days after cell grafting. 52 total samples were analyzed in 13 different groups. Each group include 4 samples and each one were analyzed as a biological replica. The intact animals were used as control of injury. The vehicle (VHC) groups were used as control of transplantation procedure. The MSC or OEC graft were injected at the day of injury (acute graft) or seven days after injury (delayed graft). The samples from engrafted animals were obtained at 2 or 7 days after cell transplantation. To determine the effects of MSC or OEC transplantation, the expression value of each engrafted sample were compared with correspondent VHC group.
