Abstract

original image

Aus dem Gehirn lebender Tiere können Stamm-/Vorläuferzellen mithilfe von Antikörperkonjugaten magnetischer Nanopartikel (Ab-MNPs) extrahiert werden. Wenn Ab-MNPs in Rattengehirn injiziert werden, lagern sich die Stammzellen an diese an und können auf magnetischem Weg isoliert werden. Außerhalb des Körpers können sie sich zu Neurosphären entwickeln und zu verschiedenen Zellarten differenzieren, während die Ratten gesund weiterleben.
