Zusammenfassung
Die Limbusstammzelltransplantation stellt eine der größten Herausforderungen in der chirurgischen Therapie von Oberflächenerkrankungen dar. Während Patienten mit einseitiger oder partieller Limbusstammzellinsuffizienz (LSI) mit autologen lamellären Limbustransplantaten vom Partnerauge versorgt werden, kann bei fortgeschrittener beidseitiger, aber noch partieller LSI eine Ex-vivo-Expansion autologer Limbusstammzellen auf Amnionmembran durchgeführt werden. Dagegen kann die beidseitige komplette LSI nur durch Transplantation allogenen Limbusgewebes mit großen immunologischen Risiken behandelt werden. Die allogene Limbusstammzelltransplantation wurde in den letzten Jahren durch Kombination mit Mitomycin C und Amnionmembrantransplantation erfolgreich weiterentwickelt. Während grundlagenwissenschaftlich zunächst an einer Transdifferenzierung von Knochenmarksstammzellen zu epithelialen Zellen gearbeitet wurde, gab es zuletzt vielversprechende Ansätze zur Verwendung von Haarfollikelstammzellen als Zellquelle. Die Erforschung der Limbusstammzellnische schließlich führt zu einem besseren Verständnis der natürlichen Wachstumsbedingungen von Limbusstammzellen, ein entscheidender Baustein in der Verbesserung der Ex-vivo-Kultur.
Abstract
The transplantation of limbal stem cells is one of the most challenging surgical approaches in ocular surface reconstruction. Partial and unilateral limbal stem cell insufficiency (LSCI) can be treated by fractionated abrasion or autologous limbal stem cell transplantation from the fellow eye. In cases of advanced bilateral and partial LSCI, ex vivo expansion of limbal stem cells on amniotic membranes or fibrin can be performed but all patients with complete bilateral LSCI must rely on allogenic limbal stem cell transplantation with high immunological risks. Attempts to combine allogenic limbal stem cell transplantation with mitomycin C and amniotic membrane transplantation are promising. In the laboratory, attempts to transdifferentiate bone marrow stem cells into corneal epithelial cells have been without success. Nonetheless, transdifferentiation of hair follicle stem cells into corneal epithelial cells looks promising. In parallel, research on the limbal stem cell niche is ongoing to elucidate the natural environment of limbal stem cells in order to improve ex vivo culture.
