Ici, une méthode facile à suivre pour cultiver in vitro des cellules épithéliales pigmentaires primaires de la rétine porcine est présentée.

Les troubles liés à l’EPR restent une partie importante du mélange des maladies, mais sans restes efficaces dans la culture virtuelle de cellules primaires de l’EPR pour servir de bon modèle pour les études physiologiques et pathologiques des troubles liés à l’EPR. Dans ce protocole, nous fournissons un protocole facile à suivre pour la culture de CPI primaires, qui pourrait rapidement restaurer et maintenir les caractéristiques RP ultérieures, nous croyons qu’en utilisant cette méthode, les gens pourraient rapidement générer des cellules RP à partir d’études de macistate et de criblages de médicaments protecteurs qui pourraient faciliter le développement de nouveaux traitements pour les troubles RPE. Une démonstration étape par étape de la valeur rendra cette méthode beaucoup plus facile à reproduire dans différents laboratoires qui souhaitent étudier les cellules RP.

Pour commencer à décongeler l’enzyme de digestion tissulaire malaquad et stériliser 1X PBS. Complété par 2% de pénicilline et 2% de streptomycine en filtrant la solution à travers une unité filtrante à seringue de 0,22 micromètre. Lavez les puits de la plaque de culture et des inserts transwell avec 1X PBS.
