mesenchymal stem cells as an alternative for schwann cells in rat spinal cord injury

چکیده
background: spinal cord has a limited capacity to repair therefore, medical interventions are necessary for treatment of injuries. transplantation of schwann cells has shown a great promising result for spinal cord injury (sci). however, harvesting schwann cell has been limited due to donor morbidity and limited expansion capacity. furthermore, accessible sources such as bone marrow stem cells have drawn attentions to themselves. therefore, this study was designed to evaluate the effect of bone marrow-derived schwann cell on functional recovery in adult rats after injury. methods: mesenchymal stem cells were cultured from adult rats’ bone marrow and induced into schwann cells in vitro. differentiation was confirmed by immunocytochemistry and rt-pcr. next, schwann cells were seeded into collagen scaffolds and engrafted in 3 mm lateral hemisection defects. for 8 weeks, motor and sensory improvements were assessed by open field locomotor scale, narrow beam, and tail flick tests. afterwards, lesioned spinal cord was evaluated by conventional histology and immunohistochemistry. results: in vitro observations showed that differentiated cells had schwann cell morphology and markers. in this study, we had four groups (n = 10 each): laminectomy, control, scaffold and scaffold + schwann cells. locomotor and sensory scores of cell grafted group were significantly better than control and scaffold groups. in histology, axonal regeneration and remyelination were better than control and scaffold groups. conclusion: this study demonstrates that bone marrow-derived schwann cells can be considered as a cell source for schwann cells in sci treatment.

Spinal cord injury (SCI) is a neurologic disorder that have a significant impact on quality of life, life expectancy, and economic burden. SCI leads to irreversible neuronal loss and ultimately leads to paralysis. Mesenchymal stem cells (MSCs) are a promising source for cellular therapy because they have possessed the capacity of self-renewal and differentiation to several distinct mesenchymal ...

Spinal cord injury (SCI) represents one of the most complicated and heterogeneous pathological processes of central nervous system (CNS) impairments, which is still beyond functional regeneration. Transplantation of mesenchymal stem cells (MSCs) has been shown to promote the repair of the injured spinal cord tissues in animal models, and therefore, there is much interest in the clinical use of ...
