    • Cell seeding density is a critical determinant for copolymer scaffolds-induced bone regeneration 

      Yassin, Mohammed Ahmed; Leknes, Knut N.; Pedersen, Torbjørn Østvik; Xing, Zhe; Sun, Yang; Lie, Stein Atle; Finne-Wistrand, Anna; Mustafa, Kamal Babikeir Eln (Peer reviewed; Journal article, 2015-11)
      Constructs intended for bone tissue engineering (TE) are influenced by the initial cell seeding density. Therefore, the objective of this study was to determine the effect of bone marrow stromal stem cells (BMSCs) density ...
    • Endothelial microvascular networks affect gene-expression profiles and osteogenic potential of tissue-engineered constructs 

      Pedersen, Torbjørn Østvik; Blois, Anna L; Xing, Zhe; Xue, Ying; Sun, Yang; Finne-Wistrand, Anna; Akslen, Lars A.; Lorens, James B.; Leknes, Knut N.; Fristad, Inge; Mustafa, Kamal Babikeir Eln (Peer reviewed; Journal article, 2013-05-17)
      Introduction: A major determinant of the potential size of cell/scaffold constructs in tissue engineering is vascularization. The aims of this study were twofold: first to determine the in vitro angiogenic and osteogenic ...
    • Hormone spiral in treatment of progesterone-induced stomatitis 

      Sandbakk, Frank-Jakob; Løes, Sigbjørn Suk; Pedersen, Torbjørn Østvik (Journal article; Peer reviewed, 2020)
      Hormonal changes in the menstrual cycle may cause autoimmune progesterone-induced stomatitis. This case illustrates that insertion of a hormone spiral can be a treatment option to reduce mucosal lesions and symptoms.
    • In vivo host response and degradation of copolymer scaffolds functionalized with nanodiamonds and bone morphogenetic protein 2 

      Suliman, Salwa; Sun, Yang; Pedersen, Torbjørn Østvik; Xue, Ying; Nickel, Joachim; Waag, Thilo; Finne-Wistrand, Anna; Steinmüller-Nethl, Doris; Krueger, Anke; Costea, Daniela Elena; Mustafa, Kamal Babikeir Eln (Peer reviewed; Journal article, 2016-03)
      The aim is to evaluate the effect of modifying poly[(l-lactide)-co-(ε-caprolactone)] scaffolds (PLCL) with nanodiamonds (nDP) or with nDP+physisorbed BMP-2 (nDP+BMP-2) on in vivo host tissue response and degradation. The ...
