The study of spinal cord regeneration in the phylogenetic scale is likely to help us in the understanding of the problem in the human situation. After spinal transection in lizards, histological changes in the spinal cord were studied and correlated with functional recovery. Some changes in spinal cord, suggestive of regeneration between the two stumps were observed. The recovery of function di...

Background: Following spinal cord injury, reactive astrocytes upregulate chondroitin sulfate proteoglycans (CSPGs) which act as a barrier to neuronal repair and regeneration. Therefore, enzymatic digestion of CSPGs by chondroitinase ABC (cABC) is a key strategy in the treatment of spinal cord injury. Furthermore, cABC has been shown to attenuate post spinal cord injury inflamma...

spinal cord injury (sci) in humans remains a devastating and incurable disorder. a very important obstacle in axonal regeneration after spinal cord injury is astroglial scaring. the use of self-assembling peptide nanofiber, a hydrogel mimicking extracellular matrix, has been suggested as a scaffold for spinal cord regeneration and inhibition of astrogliosis. however, neurogenesis potential of l...

The recovery of stepping ability following a spinal cord injury may be achieved by restoring anatomical connectivity within the spinal cord. However, studies of locomotor recovery in animals with complete spinal cord transection suggest that the adult mammalian spinal cord can acquire the ability to generate stepping after all descending input is eliminated and in the absence of neuronal regene...

Introduction: There are several spinal cord injury models available for studying axonal repair in vivo [1] however, these studies are restricted to functional or behavioural changes [2] or tissue level pathologic changes detectable by MRI [3] and by histology [4]. In vitro models that use dissociated neurons provide useful information about extrinsic factors and substrates that promote neural c...

spinal cord injury (sci) leads to a significant health problem associated with a broad range of secondary complications and disabilities. in this regard, animal models can help us to understand the pathobiology of sci and evaluate the effects of potential treatments for sci. in contusion models of sci, different devices including surgical spring-loaded clips, balloons, forceps, weights and the ...

Following spinal cord injury in rats, FK506 is able to protect local nerve tissue, promote neural regeneration, reduce neuronal apoptosis and accelerate the recovery of spinal cord functions. Nerve growth factor (NGF) is important in the regulation of central and peripheral nerve cell regeneration, growth differentiation and functions. Previous studies have shown that FK506 and NGF exhibit a sy...

BACKGROUND Among the vertebrates, teleost and urodele amphibians are capable of regenerating their central nervous system. We have used zebrafish as a model to study spinal cord injury and regeneration. Relatively little is known about the molecular mechanisms underlying spinal cord regeneration and information based on high density oligonucleotide microarray was not available. We have used a h...

Objective- The aim of this study was to demonstrate the efficacy MSCs transplantation in combination with low level laser irradiation (low level laser irradiation) in repair of experimental acute spinal cord injury. Design- Experimental study. Animals- 28 adult male Wistar Rats. Procedures- A ballon- compression technique was used to produce an injury at the T8-T9 level of spi...

Reports based primarily on anatomical evidence suggest that olfactory ensheathing glia (OEG) transplantation promotes axon regeneration across a complete spinal cord transection in adult rats. Based on functional, electrophysiological, and anatomical assessments, we found that OEG promoted axon regeneration across a complete spinal cord transection and that this regeneration altered motor respo...
