Culture of ratretinal pigment epithelium

Abstract

A method of preparing monolayer cultures of retinal pigment epithelium from normal pigmented neonatal rats is described. Critical features include incubating the eyes in balanced salt solution and treating with trypsin before dissecting the eyes. The tissue also has been cultured from RCS rats with inherited retinal degeneration. Since the pigment epithelium has been shown to be the primary site of action of the gene for retinal dystrophy in the RCS rat, the method should be useful in studying the defect(s) associated with this mutation.
