Jährlich erkranken etwa eine halbe Million Menschen in Deutschland an Krebs. Trotz der Existenz effektiver Therapiemöglichkeiten für viele Krebsarten bleiben zahlreiche Fragen zur Krankheitsentwicklung unbeantwortet. Warum entsteht ein Tumor? Welche Faktoren begünstigen das Wachstum von Krebszellen? Weshalb breiten sich Metastasen im Laufe der Zeit auf weitere Organe aus? Die bislang hauptsächlich verwendeten Tiermodelle bilden die tatsächlichen Abläufe im menschlichen Körper nur begrenzt ab. Das Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS in Dresden hat in Zusammenarbeit mit dem Fraunhofer-Institut für Toxikologie und Experimentelle Medizin ITEM in Hannover sowie der Universität Regensburg spezielle Mikrosysteme entwickelt. Darin untersuchen sie nun Gewebeschnitte von Tumoren oublr icdlmosvgumycr Johjoeepjav.
