Morphological comparison between in vivo RPE, freshly excised RPE and tRPE cells. A) Melanotic RPE in vivo morphology. B) Photograph of a confluent passage 1 primary melanotic RPE culture with the inset as a close-up. C) Photograph of passage 5 primary RPE cells displaying a polygonial morphology. D) Photograph of passage 102 tRPE cells which were pigmented by feeding them exogenous melanosomes. E) Photograph of confluent passage 102 tRPE cells grown on bovine corneal endothelial extracellular matrix (BCE-ECM).
