Neuartiges Kontrastmittel verspricht tiefe Einblicke in das Schicksal von Zellen

(PresseBox) (Berlin, )
Das Schicksal bestimmter Zellen in tiefliegenden Geweben mit sehr geringen Mengen eines von außen anschaltbaren Kontrastmittels zu verfolgen – das war bislang kaum vorstellbar. Doch ein neues Kontrastmittel auf Basis von Gas-Vesikeln bringt dieses Ziel nun in greifbare Nähe: Das von Forschern des Leibniz-Forschungsinstituts für Molekulare Pharmakologie (FMP) in Berlin und des California Institute of Technology in Pasadena entwickelte Kontrastmittel wurde speziell für MRT und Ultraschall konzipiert. Da es von Zellen selbst hergestellt werden kann, wird man künftig Krankheitsprozesse visualisieren können, die bisher im Verborgenen blieben. Die Arbeit verspricht eine kleine Revolution für die Grundlagenwissenschaften und wurde jetzt in „Nature Vynbjhukq“ wnordhmuywlkft.
