  1. 21. Toward a tissue engineered blood vessel. Cell cultivation, hemodynamic influences and matrix production

    Författare :Sepideh Heydarkhan-Hagvall; Göteborgs universitet; []
    Nyckelord :tissue engineered blood vessel; co-culture vascular cells; angiogenic factors; ; hemodynamic; extracellular matrix; stem cells;

    Sammanfattning : Cardiovascular diseases are the leading causes of mortality in the western world. Thereplacement or repair of diseased blood vessels with human autografts (vein or arteries) orsynthetic vascular grafts (ePTFE or Dacron) has become a routine treatment. Autologous graftsare not always available in all patients. LÄS MER

  3. 22. Evaluating an experimental model consecutive to abdominal wall hernia repair outcome

    Författare :Annika Winsnes; Karin Strigård; Ulf Gunnarsson; Peter Falk; Birgit Stark; Henrik Thorlacius; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hernia; mesh; luciferase; full thickness skin grafts; mice; IPOM; onlay; reinforcement materials; abdominal wall; Bråck; nät; luciferas; fullhudstransplantat; FTSG; möss; IPOM; onlay; förstärkningsmaterial; bukvägg; Surgery; kirurgi;

    Sammanfattning : Background: Abdominal wall hernia is a common surgically treated condition. Patients with primary umbilical hernia are operated with suture or mesh repair, but recurrence and complication rates have been debated.Larger abdominal wall hernias need implantation of reinforcing material for repair. Synthetic implants are dominating. LÄS MER

  4. 23. Studies on the interaction of human cells with transplantable materials for skin repair and cardiovascular surgery

    Författare :Katarina Jansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cell culture; Keratinocytes; Fibroblasts; Endothelial cells; Reepithelialization; In vitro endothelialization; Tissue engineering; Biomaterial: Dermal substitute; Synthetic vascular graft; Heart valve bioprosthesis;

    Sammanfattning : Tissue engineering is becoming an important field for the development of new tissues in vitro for replacement of diseased or worn out parts of the body. This thesis describes some characteristics of cultured human cells seeded on transplantable materials for skin repair and cardiovascular surgery. LÄS MER

  5. 24. Interactions between leukocytes, platelets and the endothelium in vein graft failure

    Författare :Chi-Nan Tseng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Autologous venous grafts are preferred conduits in bypass surgery due to their length, easy harvesting, and feasibility. However, development of intimal hyperplasia decreases long-term patency rate in venous grafts prompting close clinical surveillance and further intervention. LÄS MER

  7. 25. Auxiliary Cells for the Vascularization and Function of Endogenous and Transplanted Islets of Langerhans

    Författare :Liza Grapensparr; Per-Ola Carlsson; Leif Jansson; Mia Phillipson; Aileen King; Uppsala universitet; []
    Nyckelord :Islets of Langerhans; beta cells; diabetes; transplantation; vascularization; Schwann cells; endothelial progenitor cells; neural crest stem cells; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Type 1 diabetes develops through the progressive destruction of the insulin-producing beta-cells. Regeneration or replacement of beta-cells is therefore needed to restore normal glucose homeostasis. Presently, normoglycemia can be achieved by the transplantation of whole pancreas or isolated islets of Langerhans. LÄS MER
