1. 11. Regenerative effects of mesenchymal stem cell-derived exosomes

   Författare :Xiaoqin Wang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aging; cell adhesion; cell-material interaction; exosomes; extracellular vesicles; mesenchymal stem cells; osteogenic differentiation; proliferation; regeneration; titanium;

   Sammanfattning : Mesenchymal stem cells (MSCs) play pivotal roles for bone regeneration by virtue of their osteogenic differentiation ability and immunomodulatory capacity. Recently, secretion of exosomes/extracellular vesicles (EVs) has been suggested as a new mechanism of MSC-based therapy. LÄS MER

3. 12. Mesenchymal Stem Cells in Tumor Growth Inhibition and Cartilage Differentiation

   Författare :Laura Varas; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper; Medicine human and vertebrates ; Medicin människa och djur ; mesenchymal stem cell; Biomedical sciences; tumor growth inhibition; FGF2; cartilage; integrin alpha11beta1; integrin alpha10beta1;

   Sammanfattning : The work presented in this thesis has been focused on mesenchymal stem cells (MSCs). In the two first studies, the effects of MSCs on tumor growth and development in vitro and in vivo was investigated. LÄS MER

4. 13. 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. 14. Stem cells for cardiac regeneration

   Författare :Ivana Bulatović; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Recent studies have demonstrated a turnover of cardiomyocytes throughout the adult life. Whether this regenerative potential is due to proliferation and differentiation of resident stem cells or to the dedifferentiation of adult cardiomyocytes remains unclear. LÄS MER

7. 15. Transplantation of mesenchymal stem cells and injections of microRNA as therapeutics for nervous system repair

   Författare :Mallappa K. Kolar; Lev N. Novikov; Paul J. Kingham; Mikael Wiberg; Elisabet Åkesson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spinal cord injury; peripheral nerve injury; mesenchymal stem cells; regeneration; neurotrophic factor; angiogenic factor;

   Sammanfattning : Traumatic injuries to the spinal cord (SCI) and peripheral nerve (PNI) affect several thousand people worldwide every year. At present, there is no effective treatment for SCI and despite continuous improvements in microsurgical reconstructive techniques for PNI, many patients are still left with permanent, devastating neurological dysfunction.
