Monolithic Polymeric (Composite) Materials for Tissue Engineering


Porous polymeric monolithic materials are prepared via ring-opening metathesis polymerization from suitable norborn-2-ene- and a 7-oxanorborn-2-ene-based cross-linkers in the presence of porogenic solvents (i.e., 2-propanol and toluene) and norborn-2-enephosphonate surface-modified nanoparticles (e.g., CaCO3, hdroxyapatite). The experimental setup and the conditions chosen allowed for the manufacturing of polymeric monoliths characterized by a homogeneous distribution of the inorganic nanoparticles throughout the polymeric monolith. Depending on the nanoparticle content, the macropore diameters can be varied in the 30-400 mm regime. The thus prepared scaffolds are then seeded with mesenchymal stem cells and subjected to either osseous or adipogenic cell differentiation. Current research focuses on the surface-immobilization of the supports with suitable messenger molecules that allow for tailoring both cell adhesion and differentiation. In-vitro and in-vivo cell experiments are carried out by our medical partners.
