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...

The olfactory ensheathing cell is a specialized glial cell that assists in growth of the axons of the olfactory sensory neurons as they are generated and regenerated throughout adult life. There is increasing evidence in animal models that transplantation of olfactory ensheathing cell promotes recovery after transplantation into the injured spinal cord. Olfactory ensheathing cell transplants ha...

We report a rare case of olfactory ensheathing cell tumor. A female presented a large soft mass extending medially to the olfactory cleft and laterally to the middle meatus in the left nasal cavity. Imaging studies confirmed a cystic mass extending superiorly into the frontal lobe, indicating that the tumor arouse from the olfactory mucosa. A subtotal resection was achieved through an endoscopi...

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 ...

BACKGROUND: The olfactory epithelium can still generate new neurons after arresting its growth and development in the human body. Axons can still be generated and pass through peripheral tissue to reach the olfactory bulb. Thus, olfactory cells have been widely used in the repair of spinal cord injury. OBJECTIVE: Using animal experiments in conjunction with a clinical study of olfactory ensheat...

background: the failure of regeneration after spinal cord injury (sci) has been attributed to axonal demyelination and neuronal death. cellular replacement and white matter regeneration are both necessary for sci repair. in this study, we evaluated the co-transplantation of olfactory ensheathing cells (oec) and embryonic stem (es) cell-derived motor neurons (esmn) on contused sci. methods: oec ...

treatment of spinal cord injury by exogenous cells has brought both successful and unsuccessful results. olfactory ensheathing cells and schwann cells have been widely used for transplantation purposes. in this study, we investigated the effects of these cells on contused spinal cord by introducing cells into subarachnoid space. fifty thousand schwann cells or olfactory ensheathing cells or a m...

background: transplantation approaches are interventions currently available to apply to the devastating problem of spinal cord injury (sci). olfactory ensheathing cell (oec) and embryonic stem cell (esc) are considered to be promising therapeutic strategies . in this study, we compared the potential use of oecs and neurally pre-differentiated escs in contusion spinal cord. methods: oecs were h...

This study aimed to examine the differences in the morphological properties and proliferation of olfactory ensheathing cells in three-dimensional culture on collagen-heparan sulfate biological scaffolds and in two-dimensional culture on common flat culture plates. The proliferation rate of olfactory ensheathing cells in three-dimensional culture was higher than that in two-dimensional culture, ...
