Mit einem Polymer-Chip und menschlichen Plazenta- und Stammzellen entwickeln Empa-Forscherinnen in Zusammenarbeit mit der ETH Zürich und dem Kantonsspital St.Gallen ein System für Untersuchungen zur Entwicklungstoxizität, das künftig eine echte Alternative zu Tierversuchen darstellen soll. Der Chip erlaubt Studien zum Plazenta-Transport und der Wirkung von Substanzen auf Babys im Mutterleib. Gefragt ist ein derartiges Testsystem für die Entwicklung von neuen Medikamenten oder die Risikobewertung etwa von Nanopartikeln in der Umwelt. Die Zürcher Stiftung ProCare fördert das Projekt, das kürzlich gestartet ist.
Neue Medikamente aus Nanopartikeln, die problemlos jede Grenzfläche innerhalb unseres Körpers durchdringen können, sind eine grosse Hoffnung der Medizin.
