11. Generation of functional neural progenitors for spinal cord transplantation
Sammanfattning : Dorsal root avulsion injuries result in permanent impairment of sensory functions due to the disconnection of the peripheral nervous system from the spinal cord. Strategies aiming for the functional reconnection of sensory neurons with their targets in the spinal cord dorsal horn need to overcome the axonal growth non-permissive glial scar and provide a growth promoting environment.

12. Stem cell transplantation and regeneration after dorsal root avulsion
Sammanfattning : Spinal root avulsion leads to paralysis and loss of sensory function. Surgical methods can improve motor function and ameliorate pain but sensory recovery in adults is poor. Previous studies have shown that cell transplantation or treatment with trophic factors can improve functional outcome in rodents after dorsal root transection or crush. LÄS MER
13. Restoration of scarred vocal folds with stem cell implantation : analyses in a xenograft model
Sammanfattning : Background: Tissue defects in the vocal fold (VF) caused by trauma, surgical procedures, post radiotherapy, often heal with scar formation. The scar tissue causes stiffness of the lamina propria rendering disturbed viscoelastic properties to the VF. A scarred VF causes severe voice problems. LÄS MER
14. An ependymal cell quest : identification and functional role of spinal cord neural stem cells
Sammanfattning : Few injuries have as profound and long-lasting consequences as spinal cord injury. The primary areas of impaired function typically include sensation, mobility, bladder, bowel and sexual function. The economic, social and personal effects can also be devastating. LÄS MER
15. Merging electronics and the brain - towards a fully biocompatible neural interface
Sammanfattning : Techniques for interfacing the nervous system using chronically implanted electrodes are turning into invaluable tools for neurophysiological research and treatment of neurological disorders. These methods have been developed and refined over the last decades. LÄS MER
