Im Blut zirkulierende Tumorzellen sind die „Keimzellen“ von Brustkrebs-Metastasen. Sie sind sehr selten und ließen sich bislang nicht in der Kulturschale vermehren, was die Erforschung von Therapie-Resistenzen erschwerte. Einem Team vom Deutschen Krebsforschungszentrum (DKFZ), vom Heidelberger Stammzellinstitut HI-STEM* und dem NCT Heidelberg** ist es nun erstmals gelungen, direkt aus Blutproben von Brustkrebspatientinnen stabile Tumor-Organoide zu kultivieren. An diesen Mini-Tumoren konnten die Forschenden einen molekularen Signalweg entschlüsseln, der den Krebszellen Überleben und Therapieresistenz sichert. Mit diesem Wissen gelang es den Forschenden, einen Ansatz zu entwickeln, um die Tumorzellen im Laborexperiment dennoch gezielt auszuschalten.
