  2. 21. Fate selection in the neural crest lineage and its regulation

    Author : Natalia Akkuratova; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The neural crest is a transient embryonic progenitor cell population that generates a diverse array of cell and tissue types, including cartilage, bone, teeth, soft connective and adipose tissues, peripheral sensory and autonomic neurons, myelinating and non-myelinating Schwann cells, melanocytes, cardiac outflow tract, adrenal medulla and other derivatives. Neural crest cells start as neuroepithelial cells forming at the border of neural and non-neural ectoderm in a vertebrate embryo. READ MORE

  4. 22. Biosynthetic conduits and cell transplantation for neural repair

    Author : Jonas Pettersson; Lev Novikov; Liudmila Novikova; Mikael Wiberg; Lars Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spinal cord injury; Peripheral nerve injury; Nerve graft; Biosynthetic conduit; Nerve tissue engineering; Neural prosthesis; Neuroscience; Neurovetenskap; neurologi; Neurology; neurokirurgi; Neurosurgery;

    Abstract : Spinal cord injury results in complete failure of the central neurons to regenerate and is associated with cyst formation and enlargement of the trauma zone. In contrast to the spinal cord, axons in the injured peripheral nerve have the capacity to undergo some spontaneous regeneration. READ MORE

  5. 23. Nerve gap repair by the use of artificial conduits and cultured cells

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

    Abstract : 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.

  6. 24. Experimental spinal cord injury : development of protection and repair strategies in rats

    Author : Matthias Erschbamer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Spinal cord injury typically results in neurological deficits that can not be reversed, often leaving patients bound to a wheelchair. Current treatment strategies are not very successful. Despite many promising experimental strategies, clinical translation has so far been very limited. READ MORE

  7. 25. Stem cells for nerve repair and prevention of muscle atrophy

    Author : Dominique Schaakxs; Paul Kingham; Mikael Wiberg; Daniel Kalbermatten; Christine Radtke; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose stem cells; biomaterial; muscle; nerve injury; neuromuscular junction; regeneration; cell research; cellforskning; Medical Cell Biology; medicinsk cellbiologi;

    Abstract :   Peripheral nerve injury (PNI) is common and despite modern microsurgical techniques of repair, functional restoration is always incomplete. This results in impaired sensation and reduced motor function alongside pain and cold intolerance. READ MORE
