Zusammenfassung
Das große Potenzial von Stammzellen zur Regeneration verlorener Gewebezellen wird zunehmend in allen Fachbereichen der modernen Medizin erkannt. Abgesehen von Blutstammzellen haben Stammzellen aber noch nicht Einzug in klinische Therapieformen gehalten. Die heutigen Experimente mit Stammzellen für die Therapie von Innenohrerkrankungen sind im Bereich der Grundlagenforschung anzusiedeln. Mehrere vielversprechende Arbeiten haben bewiesen, dass morphologisch und immunologisch differenzierbare Innenohrzellen wie Haarzellen, Stützzellen und auditorische Nervenzellen, in vitro und in vivo aus verschiedenen Stammzelltypen generiert werden können. Bisher haben aber noch keine Studien funktionelle Resultate in Bezug auf das Hörvermögen oder die vestibuläre Funktion geliefert.
Abstract
The capacity of stem cells to regenerate lost tissue cells has gained recognition among physicians. Despite the successful use of blood stem cells for treating blood cancers, other stem cell types have not yet been widely introduced into clinical practice. Therapy options involving stem cells for inner ear diseases consequently have not been implemented. Nonetheless, several reports have recently been published describing the generation of morphologically and immunologically distinctive inner ear cell types—such as hair cells, supporting cells, and spiral ganglion neurons—from stem cells. Although promising, all of these studies still lack functional results regarding hearing restoration or vestibular function.
