Hier wird eine einfach zu befolgende Methode zur Kultivierung primärer retinaler Netzhaut-Pigmentepithelzellen in vitro vorgestellt.

RPE-assoziierte Störungen sind nach wie vor ein wichtiger Teil der Vermischung von Krankheiten, jedoch ohne wirksame Überreste in der virtuellen Kultur von primären RPE-Zellen, die als gutes Modell für physiologische und pathologische Studien von RPE-assoziierten Störungen dienen könnten. In diesem Protokoll stellen wir ein einfach zu befolgendes Protokoll zur Kultivierung primärer IPCs zur Verfügung, das spätere RP-Eigenschaften schnell wiederherstellen und aufrechterhalten könnte. Wir glauben, dass Menschen mit dieser Methode schnell RP-Zellen aus Makistat-Studien und den schützenden Medikamenten-Screenings erzeugen könnten, die die Entwicklung neuer Behandlungen für RPE-Störungen erleichtern könnten. Eine Schritt-für-Schritt-Demonstration des Wertes wird es viel einfacher machen, diese Methode in verschiedenen Laboratorien zu replizieren, die RP-Zellen untersuchen möchten.

Um zu beginnen, tauen Sie das Gewebeverdauungsenzym Malaquad auf und sterilisieren Sie 1X PBS. Ergänzt mit 2 % Penicillin und 2 % Streptomycin durch Filtration der Lösung durch eine 0,22 Mikrometer Spritzenfiltereinheit. Waschen Sie die Vertiefungen der Kulturplatte und der Transwell-Einsätze mit 1X PBS.
