Abstract

La présente invention concerne la préparation d’un échafaudage microstructuré correspondant à un matériau de support de type membrane biocompatible pour la culture cellulaire. La présente invention concerne également une composition comprenant l’échafaudage microstructuré et des cellules en particulier des photorécepteurs. La présente invention s’applique notamment à la préparation d’un greffon implantable pour le traitement de maladies de l’épithélium pigmentaire rétinien et de la rétine neurale. Fig. 1
