Research Interests: | The research in my group is mainly focusing on (i) the analysis of immunogeneic and inflammatory characteristics and the immumodulatory capacities of stem cells and their derivatives as well of other primary cell types for potential therapeutic application and (ii) the evaluation of inflammation and immune mediated processes by natural derived extracellular matrix structures. Cell and tissue grafts could be implemented in many fields of regenerative medicine to substitute damaged tissue and to promote the induction of self-renewing processes. Although non-foreign (autologous) cells and tissues are frequently used, several immunological problems arise by to long-term culture periods in vitro as well as by the combination with matrix structures. Due to limited sources for autologous cells and a need for their off-the-shelf availability there is a substantial interest to apply also foreign (allogeneic) cells and tissues. In this scenario rejection problems induced by adaptive immune responses have to be handled. Based on this background we are working at the following research fields: 1. Immunogenicity and immunomodulation of stem cells, their derivatives and other primary cells (e.g. endothelial cells, endothelial progenitor cells, mesenchymal stem cells, cardiac derived progenitor cells, nucleus pulposus cells) 2. Modification of immunogenicity of stem cells and their derivatives (e.g. by modulating their surface molecule expression pattern) 3. Immunomodulation of endothelial cells for application in vascular substitutes and generation of suitable models for testing small caliber vascular grafts 4. Analysis of immunomodulatory and repair function of Mesenchymal Stem cells (MSCs) of different origin and sources by developing a set of in vitro systems, like proliferation, cytotoxicity, complement activation and cytokine/chemokine release assays as well the screening in rat in vivo models 5. Studies on dimension and quality of human immune responses to xenogeneic natural extracellular matrix components |
