The Effect of Transplantation of Olfactory Ensheathing Cells on the Size of Posttraumatic Spinal Cord Cysts.

We studied the effect of transplantation of ensheathing cells obtained from the olfactory mucosa of rats and humans on the size of posttraumatic spinal cord cysts. MRI examination showed that transplantation of these cells into experimental posttraumatic cysts of the spinal cord led to a significant decrease in cyst volume and even their complete disappearance in two animals receiving transplantation of rat or human cells. These findings attested to regenerative processes developing as a result of ensheathing cell transplantation. Further studies in this field will be aimed at elucidation of the mechanisms underlying spinal cord regeneration in the area of posttraumatic cysts after transplantation of ensheathing cells.
