Signals … Webepithelium (RPE) co-cultures [2]. Under both culture conditions, rod photoreceptor development is supported, although outer segment development and maintenance is impaired in the absence of the RPE [1]. No peanut agglutinin (PNA) lectin-positive cone sheets or cone opsin-positive cone outer segments could be detected in a retina-only …
