Alginate microbeads are coagulation compatible, while alginate microcapsules activate coagulation secondary to complement or directly through FXII
Gravastrand, Caroline; Hamad, Shamal; Fure, Hilde; Steinkjer, Bjørg; Ryan, Liv; Oberholzer, José; Lambris, John D.; Lacík, Igor; Mollnes, Tom Eirik; Brekke, Ole-Lars; Rokstad, Anne Mari (Journal article; Peer reviewed, 2017)Alginate microspheres are presently under evaluation for future cell-based therapy. Their ability to induce harmful host reactions needs to be identified for developing the most suitable devices and efficient prevention ... -
Alginate Microencapsulation of Human Islets Does Not Increase Susceptibility to Acute Hypoxia
Hals, Ingrid Katrin; Rokstad, Anne Mari; Strand, Berit Løkensgard; Oberholzer, José; Grill, Valdemar (Journal article; Peer reviewed, 2013)Islet transplantation in diabetes is hampered by the need of life-long immunosuppression. Encapsulation provides partial immunoprotection but could possibly limit oxygen supply, a factor that may enhance hypoxia-induced ... -
In Vitro and In Vivo Biocompatibility Evaluation of Polyallylamine and Macromolecular Heparin Conjugates Modified Alginate Microbeads
Vaithilingam, Vijayaganapathy; Steinkjer, Bjørg; Ryan, Liv; Larsson, Rolf; Tuch, Bernard E.; Oberholzer, José; Rokstad, Anne Mari (Journal article; Peer reviewed, 2017)Host reactivity to biocompatible immunoisolation devices is a major challenge for cellular therapies, and a human screening model would be of great value. We designed new types of surface modified barium alginate microspheres, ...
