Re-pigmentation of retinal pigment epithelial (RPE) cells. Typically, continuously growing RPE cell lines lack melanin pigment (left). Non-pigmented RPE cells can be re-pigmented with controlled quantities of purified melanosomes resulting from RPE cells from light pigmentation (center) to cell cultures displaying very strong pigmentation (right) which is normally seen in the eye.
