Spinal cord injury research different types of cells. The hope is that stem cells transplanted into an injured area of the spinal cord will allow neuroregeneration. Types of cells being researched for use in SCI include embryonic stem cells, neural stem cells, mesenchymal stem cells, olfactory ensheathing cells, Schwann cells, activated macrophages, and induced pluripotent stem cells. When stem cells are injected in the area of damage in the spinal cord, they secrete neurotrophic factors, and these factors help neurons and blood vessels to grow, thus helping repair the damage. It is also necessary to recreate an environment in which stem cells will grow.
Spinal cord injury impingement on the spinal cord by a tumor or vertebral disk. Anterior cord syndrome, due to damage to the front portion of the spinal cord or reduction in the blood supply from the anterior spinal artery, can be caused by fractures or dislocations of vertebrae or herniated disks. Below the level of injury, motor function, pain sensation, and temperature sensation are lost, while sense of touch and proprioception (sense of position in space) remain intact. These differences are due to the relative locations of the spinal tracts responsible for each type of function. Brown-Séquard syndrome occurs when the spinal cord
