      Adipose-derived stem cells (ASC) have been used as an alternative to bone marrow mesenchymal stem cells (BMSC) for bone tissue engineering. However, the efficacy of ASC in bone regeneration in comparison with BMSC remains ...
    • Feasibility and utility of MRI and dynamic 18F-FDG-PET in an orthotopic organoid-based patient-derived mouse model of endometrial cancer 

      Espedal, Heidi; Berg, Hege Fredriksen; Fonnes, Tina; Fasmer, Kristine Eldevik; Krakstad, Camilla; Haldorsen, Ingfrid S. (Journal article; Peer reviewed, 2021)
      Background: Pelvic magnetic resonance imaging (MRI) and whole-body positron emission tomography-computed tomography (PET-CT) play an important role at primary diagnostic work-up and in detecting recurrent disease in ...
    • Imaging of preclinical endometrial cancer models for monitoring tumor progression and response to targeted therapy 

      Espedal, Heidi; Fonnes, Tina; Fasmer, Kristine Eldevik; Krakstad, Camilla; Haldorsen, Ingfrid S. (Peer reviewed; Journal article, 2019-11-27)
      Endometrial cancer is the most common gynecologic malignancy in industrialized countries. Most patients are cured by surgery; however, about 15% of the patients develop recurrence with limited treatment options. Patient-derived ...
    • Lack of functional normalisation of tumour vessels following anti-angiogenic therapy in glioblastoma 

      Obad, Nina; Espedal, Heidi; Jirík, Radovan; Sakariassen, Per Øystein; Rygh, Cecilie Brekke; Lund-Johansen, Morten; Taxt, Torfinn; Niclou, Simone Pierrette; Bjerkvig, Rolf; Keunen, Olivier (Peer reviewed; Journal article, 2017)
      Neo-angiogenesis represents an important factor for the delivery of oxygen and nutrients to a growing tumour, and is considered to be one of the main pathodiagnostic features of glioblastomas (GBM). Anti-angiogenic therapy ...
    • Near-Infrared Fluorescent Imaging for Monitoring of Treatment Response in Endometrial Carcinoma Patient-Derived Xenograft Models. 

      Fonnes, Tina; Strand, Elin; Fasmer, Kristine Eldevik; Berg, Hege Fredriksen; Espedal, Heidi; Sortland, Kristina; Stefansson, Ingunn; Bjørge, Line; Haldorsen, Ingfrid S; Krakstad, Camilla; Mc Cormack, Emmet (Journal article; Peer reviewed, 2020)
      Imaging of clinically relevant preclinical animal models is critical to the development of personalized therapeutic strategies for endometrial carcinoma. Although orthotopic patient-derived xenografts (PDXs) reflecting ...
    • Novel clearance of muscle proteins by muscle cells 

      Muslimovic, Aida; Friden, Vincent; Starnberg, Karin; Tenstad, Olav; Espedal, Heidi; Vukusic, Kristina; Nyström, Susanne; Wesén, Emelie; Esbjörner, Elin K; Granholm, Kristoffer; Lindahl, Bertil; Hammarsten, Ola (Journal article; Peer reviewed, 2020)
      Blood levels of cardiac troponins (cTn) and myoglobin are analysed when myocardial infarction (MI) is suspected. Here we describe a novel clearance mechanism for muscle proteins by muscle cells. The complete plasma clearance ...
    • Pretreatment of glioblastoma with bortezomib potentiates natural killer cell cytotoxicity through TRAIL/DR5 mediated apoptosis and prolongs animal survival 

      Gras Navarro, Andrea; Espedal, Heidi; Vareecal Joseph, Justin; Moncho, Laura Trachsel; Bahador, Marzieh; Gjertsen, Bjørn Tore; Kristoffersen, Einar Klæboe; Simonsen, Anne; Miletic, Hrvoje; Enger, Per Øyvind; Rahman, Mohummad Aminur; Enger, Martha Chekenya (Peer reviewed; Journal article, 2019-07-17)
      Background: Natural killer (NK) cells are potential effectors in anti-cancer immunotherapy; however only a subset potently kills cancer cells. Here, we examined whether pretreatment of glioblastoma (GBM) with the proteasome ...
    • Repurposing 18F-FMISO as a PET tracer for translational imaging of nitroreductase-based gene directed enzyme prodrug therapy
