Mit Barcodes der Zellentwicklung auf der Spur

(PresseBox) (Heidelberg, )
Darüber, wie sich Blutzellen entwickeln, existieren verschiedene Auffassungen - sie basieren jedoch fast ausschließlich auf Experimenten, die lediglich Momentaufnahmen widerspiegeln. Wissenschaftler des Deutschen Krebsforschungszentrums stellen nun im Fachjournal Nature eine neue Technik vor, mit der sich das Geschehen dynamisch erfassen lässt: Mithilfe eines "Zufallsgenerators" versehen sie Blutstammzellen mit genetischen Barcodes und können so verfolgen, welche Zelltypen aus der Stammzelle hervorgehen. Diese Technik erlaubt künftig völlig neue Einblicke in die Entwicklung unterschiedlicher Gewebe sowie in die Krebsentstehung.

Wie entsteht die Vielzahl verschiedener Zelltypen im Blut? Diese Frage beschäftigt Wissenschaftler schon lange. Nach der klassischen Vorstellung fächern sich unterschiedliche Entwicklungslinien auf wie pj znngj Fvvn.
