Hundreds of Organoids (miniature brains) were grown in the laboratories of the University of Trento to study the genetic mechanisms responsible for the most common brain cancer affecting children. The results of a collaborative research effort, coordinated by the University of Trento and carried out with Sapienza University and Ospedale pediatrico Bambino Gesù in Rome and Irccs Neuromed, were published today in Nature Communications. The study will open new perspectives of research, as the large-scale production of in vitro tumors could make it possible to perform large drug screenings to identify new brain cancer drugs
