Structural research is one of the most important analysis methods for the assessment of native, pathological, and regenerating tissue, and therefore constitutes an important basis for medical-biological research. At the Competence Center Morphology, we deal with the morphology of cells, tissue, and biomaterials in the framework of experimental and clinical projects to gain information on the structure and composition of the objects to be examined.
Morphology of Cells, Tissue and Biomaterials in Focus
The Core Facility Morphology is a cooperative laboratory of the University Clinic of Dentistry, the University Clinic for Trauma Surgery, and the Ludwig Boltzmann Institute for Experimental and Clinical Traumatology in the framework of the Austrian Cluster for Tissue Regeneration. It performs histological as well as electron microscopic reprocessing of hard and soft tissue and biomaterials.
In addition to classic histochemical colourations for a differential representation of various tissue components in tissue sections, immunohistochemical reactions are regularly executed to specifically determine their matrix composition (e.g. collagen I, II, III, fibrin), soluble substances (e.g. BMPs, MMPs), cell components (e.g. mitochondria, vimentin), cellular activities (e.g. Ki67, caspase 3), as well as the cell types (CD31, CD68, CD45) of tissue samples.
Electron microscopy offers a structural representation in the high definition, ultrastructural range (e.g. collagen matrix, fibrin network, cell surfaces, material surfaces). With these methods, the development of tissue, the state, as well as the activity, of cells and the degradation of biomaterials can be displayed. Last year, projects in the areas of dental health, osteogenesis, vascularisation, neural innervation, cartilage regeneration and organ failure were supported.
Sylvia Nürnberger received her PhD from the Department of Life Sciences of the University of Vienna and has been active in the field of tissue regeneration since her dissertation. Her main focus lies on cartilage regeneration using cell therapy and biomaterials as well as on biological adhesive research, which she undertakes at the University Clinic for Trauma Surgery and the Ludwig Boltzmann Institute for Experimental and Clinical Traumatology in the framework of the Austrian Cluster for Tissue Regeneration, in projects funded by the Austrian Science Fund FWF and Austrian Research Promotion Agency FFG. In her capacity as the Head of the Core Facility Morphology, she is interested in the interdisciplinary use of morphological and analytical methods to answer questions arising in clinical and fundamental research.
