1. 1. Regulation of Injury Induced Schwann Cell Proliferation Schwann Cell Proliferation

   Författare :Åsa Fex Svenningsen; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; estrogen; signal transduction; insulin like growth-factors; Schwann cell; peripheral; nerve regeneration; Djurfysiologi; Animal physiology; progesterone;

   Sammanfattning : The purpose of this study was to investigate injury induced proliferation of Schwann cells with emphasis of the effects of the insulin-like growth factors (IGF-I and IGF-II) and the sex hormones progesterone and estrogen. Proliferation, measured as [3H] thymidine incorporation, was studied in cultured segments of the rat sciatic nerve or through the use of the thymidine analogue bromo- deoxy-uridine (BrdU) in combination with immunocytochemistry.

3. 2. Neuron-glial Interaction in the Developing Peripheral Nervous System

   Författare :Mikael Corell; Åsa Fex Svenningsen; Klas Kullander; Helgi Schöith; Heape Anthony; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Schwann cell; nonmyelinating Schwann cell; myelinating Schwann cell; development; proliferation; differentiation; myelin; neural stem cell; central nervous system; peripheral nervous system; enteric nervous system; N-cadherin; GABA; GAD; GABA B receptor; baclofen; CGP55485; Neuroscience; Neurovetenskap; Neuroscience; Neurovetenskap;

   Sammanfattning : The nervous system, including the brain, is the most sophisticated organ in the mammalian body. In such a complex network, neuron-glial interaction is essential and controls most developmental processes, such as stem cell fate determination, migration, differentiation, synapse formation, ensheathment and myelination.

4. 3. Schwann cells and mesenchymal stem cells as promoter of peripheral nerve regeneration

   Författare :Maria Cristina Mantovani; Mikael Wiberg; Giorgio Terenghi; Susan Shawcross; Lev Novikov; Liudmila Novikova; John W Haycock; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve regeneration; Schwann cell; adult stem cell; myelin; senescence;

   Sammanfattning : The transplantation of primary Schwann cells (SC) has been shown to improve nerve regeneration. However, to monitor the survival of transplanted cells within the host, a stable labelling method is required. LÄS MER

5. 4. Tendon autografts for bridging nerve defects

   Författare :Jerker Brandt; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Surgery; orthopaedics; cell culture; graft; rat; collagen; tendon; Schwann cells; axons; Peripheral nerve regeneration; axonal outgrowth; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : A new method, where a tendon segment – a tendon autograft – was used as graft material for peripheral nerve reconstruction, was developed. Defects, 10-15 mm long, in rat sciatic nerves were bridged by various modifications of tendons. LÄS MER

7. 5. 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.
