Zusammenfassung

Der Einsatz von pluripotenten Stammzellen (PSCs) in der Zellersatztherapie des Diabetes mellitus stellt eine vielversprechende Alternative zur Insulinsubstitution dar. Die in vitro Differenzierung von humanen oder murinen embryonalen Stammzellen erzeugt reproduzierbar pankreatische Vorläuferzellen, aber bislang noch keine authentischen insulinproduzierenden Betazellen. Induzierte pluripotente Stammzellen könnten sich möglicherweise als weitere Ausgangsquelle für die Zellersatztherapie eignen. Diese patientenspezifischen Stammzellen werden durch Reprogrammierung erzeugt, akkumulieren allerdings während der Reprogrammierung genetische und epigenetische Fehler, was bisher eine humantherapeutische Anwendung ausschließt.

Abstract

The use of pluripotent stem cells (PSCs) harbours great potential for a future use in the cell replacement therapy of diabetes mellitus. The in vitro differentiation of human or mouse embryonic stem cells has yielded pancreatic progenitor cells, but not authentic insulin-producing beta cells. Induced pluripotent cells are a class of a pluripotent stem cells potentially suited as a cell source for cell replacement therapy. These patient specific pluripotent cells are generated by reprogramming but unfortunately accumulate genetic and epigenetic errors during reprogramming, precluding their use for therapeutic purposes in humans.
