1. 1. Development of biosynthetic conduits for peripheral nerve repair

   Författare :Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

   Sammanfattning : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.

3. 2. Sensory neuronal protection & improving regeneration after peripheral nerve injury

   Författare :Andrew McKay Hart; Mikael Wiberg; Angus McGrouther; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell death; TUNEL; optical disection; dorsal root ganglion; peripheral nerve; nerve conduit; Schwann cell; glial growth factor; leukaemia inhibitory factor; acetyl-L-carnitine; N-acetyl-cysteine; Neurovetenskap; Neurology; Neurologi; neurokirurgi; Neurosurgery;

   Sammanfattning : Peripheral nerve trauma is a common cause of considerable functional morbidity, and healthcare expenditure. Particularly in the ~15% of injuries unsuitable for primary repair, standard clinical management results in inadequate sensory restitution in the majority of cases, despite the rigorous application of complex microsurgical techniques.

4. 3. Nerve gap repair by the use of artificial conduits and cultured cells

   Författare :Daniel Kalbermatten; Mikael Wiberg; Ulrich Mennen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose stem cells; cell matrix; fibrin; nerve conduit; nerve gap; Surgery; Kirurgi; kirurgi; Surgery;

   Sammanfattning : Peripheral nerve injuries are often associated with loss of nerve tissue and require autologous nerve grafts to provide a physical substrate for axonal growth. This thesis investigates the use of fibrin as both a tubular conduit to guide nerve regeneration and also as a matrix material to suspend various regenerative cell types within/on poly-3-hydroxybutyrate (PHB) nerve conduits.

5. 4. Repair and Reconstruction of Peripheral Nerve Injuries. Treatment with G-CSF and Stromal Vascular Fraction

   Författare :Hanna Frost; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve injuries; nerve regeneration; reconstructive surgical procedures; diabetes mellitus; rat sciatic nerve; granulocyte colony-stimulating factor; stromal vascular fraction; electrospinning; rats; Schwann cells;

   Sammanfattning : While surgery is a cornerstone in treatment of peripheral nerve injuries, it is not a comprehensive approach, and outcome is unsatisfactory, especially sensory function. The present aim was to translate recent findings about stem- and progenitor cells to improve regenerative outcome, where the cells have to be autologous, available within the same surgical procedure, and minimally manipulated.

7. 5. The use of adipose derived stem cells in spinal cord and peripheral nerve repair

   Författare :Mallappa K Kolar; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spinal cord injury; peripheral nerve injury; adipose derived stem cells; regeneration; neurotrophic factor; angiogenic factor;

   Sammanfattning : Clinically, injuries affecting the spinal cord or peripheral nerves can leave those affected with severe disability and, at present, there are limited options for treatment. Peripheral nerve injury with a significant gap between the proximal and distal stumps is currently treated with autologous nerve grafting but this is limited by availability of donor nerve and has associated morbidities.
