Zusammenfassung

Die Kultivierung und Expansion von primären kornealen Zellen verzeichnet große Fortschritte in den letzten Jahren. Die Transplantation von kultivierten limbalen Epithelzellen ist bereits eine etablierte, erfolgreiche Therapie der okulären Oberfläche. Kultivierte korneale Endothelzellen werden derzeit in einer klinischen Studie in Japan getestet. Stromale Keratozyten können in vitro expandiert werden. Auch andere Stammzellgruppen können zu kornealen Zellen differenzieren und werden in Tiermodellen auf ihre Eignung überprüft. Bis zu ihrem klinischen Einsatz müssen allerdings noch Prozesse optimiert und vereinheitlicht, die Differenzierungseffizienz gesteigert und ethische Probleme adressiert werden. In diesem Übersichtsartikel fassen wir die aktuellen Entwicklungen im Bereich der kornealen Zelltherapie zusammen.

Abstract

In recent years, the cultivation and expansion of primary corneal cells has made significant progress. The transplantation of cultured limbal epithelial cells represents a successful and established treatment of the ocular surface. Cultivated corneal endothelial cells are undergoing a clinical trial in Japan. Stromal keratocytes can now be expanded in vitro. A wide range of stem cell sources is being tested in vitro and animal models for their possible application in corneal cell therapy. This article gives an overview of recent advancements and prevailing limitations for the use of different cell sources in the therapy of corneal disease.
