    Sammanfattning : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Transplanting bone graft from one site in the patient to the site of fracture or bone void, i.e. LÄS MER

    Sammanfattning : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Autologous bone grafting is commonly used throughout the world. LÄS MER

  4. 4. Human embryonic stem cells for bone engineering applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Giuseppe Maria de Peppo; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

    Sammanfattning : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. LÄS MER

  5. 5. The Anabolic - Anti-catabolic Paradigm of Augmenting Skeletal Regeneration: A Bone Quality Perspective

    Detta är en avhandling från Department of Biomedical Engineering, Lund university

    Författare :Neashan Mathavan; [2017-05-08]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone fracture; Fracture healing; bone quality; Bone biomechanics; bone morphogenetic protein-7; Zoledronate; skeletal regeneration;

    Sammanfattning : Successful fracture repair is a complex series of coordinated processes leading to regeneration of new bone to bridge the fracture site, remodelling of the newly formed bone and restoration of skeletal function. Disruption of these processes occurs in approximately 10% of all fractures and leads to delayed or failed healing requiring surgical interventions, increased complication rates, prolonged rehabilitation and high morbidity.
