Our department develops and validates cell therapeutic methods in terms of safety, feasibility and efficiency. For this purpose, we maintain a plurality of model systems that enable the preclinical testing of novel concepts according to very strict quality criteria. In this manner, we ensure a high predictive value of our results for clinical implementation. A particular emphasis is on cell therapeutic methods for ischemic diseases like stroke and myocardial infarction, but also on methods for preventing degeneration and ageing of cells. Moreover, we investigate the "sleeping" potential of stem cells. We offer methods for the isolation and purification of cells from blood and tissues. We also develop special treatment methods employing T cell clones and natural killer cells for the treatment of tumors.
