introduction: spinal cord injuries (sci) lead to permanent irreversible functional deficits.  poor prognosis of patients is the motivation of searching a treatment for the chronic injury.  planting stem cells provides us with a promising strategy. in the meanwhile, the use of olfactory ensheathing cells (oecs) has shown very good results.  this study aims at evaluating the effect of transplante...

Tenascin-R (TN-R) is a neural specific protein and an important molecule involved in inhibition of axonal regeneration after spinal cord injury (SCI). Here we report on rabbit-derived TN-R polyclonal antibody, which acts as a TN-R antagonist with high titer and high specificity, promoted neurite outgrowth and sprouting of rat cortical neurons cultured on the inhibitory TN-R substrate in vitro. ...

The injured adult mammalian spinal cord shows little spontaneous recovery after injury. In the present study, the contribution of projections in the dorsal half of the spinal cord to functional loss after adult spinal cord injury was examined, together with the effects of transgenic cellular delivery of neurotrophin-3 (NT-3) on morphological and functional disturbances. Adult rats underwent bil...

Spinal cord injury (SCI), usually resulting in severe sensory and motor deficits, is a major public health concern. Adipose‑derived stem cells (ADSCs), one type of adult stem cell, are free from ethical restriction, easily isolated and enriched. Therefore, ADSCs may provide a feasible cell source for cell‑based therapies in treatment of SCI. The present study successfully isolated rat ADSCs (rA...

spinal cord injury (sci) results in the damage of motor and sensory pathways. the molecular and cellular structure of the injury milieu has been shown to be vital for endogenous regeneration in most tissues. regeneration of injured central nervous system (cns) is limited by damaged cell environment. biomaterial scaffolds can reconstruct injured cns tissue following sci by promoting the migratio...

traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

Spinal cord injuries (SCI) often lead to persistent neurological dysfunction due to failure in axon regeneration. Unfortunately, currently established treatments, such as direct drug administration, do not effectively treat SCI due to rapid drug clearance from our bodies. Here, we introduce a three-dimensional aligned nanofibers-hydrogel scaffold as a bio-functionalized platform to provide sust...

Background: Neutrophil infiltration plays an important role in inflammatory reactions following spinal cord injury (SCI) and these cells cause substantial secondary tissue damage. The purpose of this study was to determine the effect of oleuropein (OE) on myeloperoxidase (MPO) activity as an index of neutrophil infiltration. Methods: Rats were randomly divided into four groups of 7 rats each as...

Conventional magnetic resonance imaging (MRI) can detect hemorrhage, edema, syrinx, and spinal cord atrophy, but not axonal disruption after spinal cord injury (SCI). We previously demonstrated that diffusion tensor tractography (DTT) could depict axonal disruption after hemisection SCI in common marmosets. In the present study, to determine the relationship between DTT results and functional r...
