OBJECTIVE Nerve regenerative is a complex problem and cell therapy strategies are being developed to enhance axonal regeneration. One approach is to transplant peripheral myelin-forming cells (Schwann cells or olfactory ensheathing cells) that can secrete neurotrophic factors and participate in remyelination of regenerated axons. The objectives of this report are to first review the basic regen...

BACKGROUND Olfactory ensheathing cell transplantation is a promising treatment for spinal cord injury. Diffusion tensor imaging has been applied to assess various kinds of spinal cord injury. However, it has rarely been used to evaluate the beneficial effects of olfactory ensheathing cell transplantation. This study aimed to explore the feasibility of diffusion tensor imaging in the evaluation ...

OBJECTIVE To identify global research trends in transplantation of neural stem cells, Schwann cells and olfactory ensheathing cells for spinal cord injury. DATA RETRIEVAL We performed a bibliometric analysis of studies on transplantation of neural stem cells, Schwann cells and olfactory ensheathing cells for spinal cord injury published from 2002 to 2011 and retrieved from the Web of Science,...

Numerous studies in animals have shown the unique property of olfactory ensheathing cells to stimulate regeneration of lesioned axons in the spinal cord. In a Phase I clinical trial, we assessed the safety and feasibility of transplantation of autologous mucosal olfactory ensheathing cells and olfactory nerve fibroblasts in patients with complete spinal cord injury. Six patients with chronic th...

multiple sclerosis (ms) causes loss of the myelin sheath, which leads to loss of neurons. regeneration of myelin sheath stimulates axon regeneration and neurons’ survival. in this study, olfactory ensheathing cell (oec) transplantation is investigated to restore myelin sheath in an experimental model of ms in male mice.oecs were isolated from the olfactory mucosa of seven-day-old infant rats an...

Olfactory ensheathing cells, the glial cells of the olfactory nervous system, exhibit unique growth-promoting and migratory properties that make them interesting candidates for cell therapies targeting neuronal injuries such as spinal cord injury. Transplantation of olfactory cells is feasible and safe in humans; however, functional outcomes are highly variable with some studies showing dramati...

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 effe...

OBJECTIVE We sought to study the yield of olfactory ensheathing cells from biopsies of the mucosa of the nasal septum. These specialized cells encourage regeneration of nerves of the central nervous system and may be of value for spinal cord and nerve injuries. METHODS We undertook a prospective observational study of biopsies of nasal mucosa by endonasal dissection of the mucosa of the nasal...

We demonstrated recently that transplantation of olfactory ensheathing cells from the nasal olfactory mucosa can promote axonal regeneration after complete transection of the spinal cord in adult rat. Ten weeks after transection and transplantation there was significant recovery of locomotor behaviour and restoration of descending inhibition of spinal cord reflexes, accompanied by growth of axo...

The aim of this study was to determine the effectiveness and safety of transplantation of olfactory ensheathing cells for functional repair of the spinal cord. An olfactory bulb was obtained from a 4- to 5-month-old aborted fetus, and it was digested into single olfactory ensheathing cells and then cultured and purified for 1 to 2 weeks. Under general anesthesia, these single-cell suspensions o...
