Method of producing retinal pigment epithelial cell

Abstract

Provided are a production method of retinal pigment epithelial (RPE) cells that improves differentiation induction efficiency of pluripotent stem cells into RPE cells, and can provide highly pure RPE cells by a simple and easy operation in a short period, a culture method of RPE cells that can stably grow and culture a cell, a toxicity/efficacy evaluation method using RPE cells useful for transplantation therapy, and a therapeutic drug for a retinal disease. The invention relates to a production method of RPE cells, comprising adhesion culture of human pluripotent stem cells using a culture substrate coated with a laminin-E8 fragment, a culture method of RPE cells, comprising adhesion culture of RPE cells using a culture substrate coated with a laminin-E8 fragment, a toxicity or efficacy evaluation method using RPE cells obtained by producing or culturing by the method, and a therapeutic drug for a retinal disease, containing the RPE cells.
