  Site-Directed Immobilization of Bone Morphogenetic Protein 2 to Solid Surfaces by Click Chemistry Claudia Siverino¹, Barbara Tabisz², Tessa Lühmann³, Lorenz Meinel³, Thomas Müller⁴, Heike Walles^1,2, Joachim Nickel^{1,2 1}Fraunhofer-Institut für Grenzflächen- und Bioverfahrenstechnik (IGB), Translationszentrum Würzburg 'Regenerative Therapien für Krebs- und Muskuloskelettale Erkrankung', Institutsteil Würzburg, ²Lehrstuhl für Tissue Engineering und Regenerative Medizin, Universitätsklinikum Würzburg, ³Lehrstuhl für Pharmazeutische Technologie und Biopharmazie, Universität Würzburg, ⁴Lehrstuhl für molekulare Pflanzenphysiologie und Biophysik, Julius-von-Sachs Institut für Biowissenschaften, Universität Würzburg Biomaterials doped with Bone Morphogenetic Protein 2 (BMP2) have been used as a new therapeutic strategy to heal non-union bone fractures. To overcome side effects resulting from an uncontrollable release of the factor, we propose a new strategy to site-directly immobilize the factor, thus creating materials with improved osteogenic capabilities.

  Generation of a Three-dimensional Full Thickness Skin Equivalent and Automated Wounding Angela Rossi*¹, Antje Appelt-Menzel*¹, Szymon Kurdyn¹, Heike Walles^1,2, Florian Groeber^{2 1}Department for Tissue Engineering and Regenerative Medicine, University Hospital Würzburg, ²Translational Center Würzburg, Regenerative Therapies in Oncology and Musculoskelettal Disease, Würzburg Branch of the Fraunhofer-Institute Interfacial Engineering and Biotechnology, IGB The goal of this protocol is to build up a three-dimensional full thickness skin equivalent, which resembles natural skin. With a specifically constructed automated wounding device, precise and reproducible wounds can be generated under maintenance of sterility.

  Tissue Engineering of a Human 3D in vitro Tumor Test System Corinna Moll*¹, Jenny Reboredo*¹, Thomas Schwarz¹, Antje Appelt¹, Sebastian Schürlein¹, Heike Walles¹, Sarah Nietzer^{1 1}Department of Tissue Engineering and Regenerative Medicine, University Hospital Würzburg Methods to create human 3D tumor tissues as test systems are described. These technologies are based on a decellularized Biological Vascularized Scaffold (BioVaSc), primary human cells and a tumor cell line, which can be cultured under static as well as under dynamic conditions in a flow bioreactor.
