A model for de novo pigmentation of amelanotic retinal pigment epithelial cells

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Retinal Pigment Epithelial (RPE) cells perform critical functions in the visual cycle. Their melanin pigmentation, which is organized into specialized compartments – melanosomes, is highly critical for proper vision. A chemical method to induce pigmentation in a non‐pigmented model of ARPE‐19 cells was applied using L‐DOPA as a ...
