This invention discloses methods to attach and grow a monolayer of cultured human retinal pigment epithelial cells (RPE) for use in implantation into the brain as a treatment for Parkinson's disease. The invention will enable the delivery of the transplanted RPE cells in microcarriers composed of intergratable or degradable substrates, including glass, plastic, polymer gels, gelatin and collagen, and glycosaminoglycans (GAGS). The invention involves the coating of the microcarrier surface with diamond-like carbon, alone or in combination with attachment factors such as laminin, fibronectin, RGDS, and extracellular matrix to increase the attachment of the RPE to the surface. Additionally the invention discloses the use of bFGF conjugated with polycarbophil, EGF conjugated with polycarbophil and heparin sulfate as also being incorporated into the micro carrier to augment attachment and proliferation of RPE during transplantation.

L'invention concerne des méthodes permettant de fixer et de développer une monocouche de cellules épithéliales pigmentaires de la rétine humaine (RPE) en vue d'une implantation dans le cerveau pour traiter la maladie de Parkinson. L'invention permet d'administrer les cellules RPE dans des micro-supports constitués par des substrats intégrables ou dégradables, notamment de verre, de plastique, de gels polymères, de gélatine ou de collagène, ainsi que des glycosaminoglycanes (GAG). L'invention consiste à revêtir la surface des micro-supports d'un carbone de type diamant de manière isolée ou en combinaison avec des facteurs de fixation tels que la laminine, la fibronectine, RGDS et une matrice extracellulaire en vue d'augmenter la fixation des cellules RPE à la surface. En outre, l'invention concerne l'utilisation d'un bFGF conjugué avec un polycarbophile, d'un EGF conjugué avec un polycarbophile et d'un sulfate d'héparine, lesquels sont également incorporés dans le micro-support en vue d'une augmentation de la fixation et de la prolifération des cellules RPE pendant une transplantation.
