A seaweed's color is determined by the combination of pigments housed in its chloroplasts or plastids (a specialized substructure within its cells).

When Kaufman, Zon and colleagues looked to see what was different about these early cancer cells, they found that crestin and the other activated genes are the same ones turned on during zebrafish embryonic development — specifically, in the stem cells that give rise to the pigment cells known as melanocytes, within a structure called the neural crest.

In reptiles, amphibians, and other groups, color mostly comes from chromatophores — cells within the skin that hold color - producing pigment molecules.

Scientists currently know very little about why these particular cells within the eye do not survive with age and cause problems that lead to a disease called Pigment Dispersion Syndrome (PDS).

Close to such depigmented RPE cells, highly pigmented macrophages identified by CD68 staining were located between Bruch's membrane and the RPE and in the subretinal space or within the choroid.The total number of lipofuscin granules was counted in the cytoplasm of RPE cells from untreated and treated monkeys.

Donor cells comprising the semi-continuous subretinal layer possessed intracellular pigment granules (confirmed on semi-thin sections) similar to host RPE cells, unlike those that migrated within the neurosensory retina, which remained unpigmented (Figure 5B).

In many forms of human retinal disease, including age - related macular degeneration (AMD), the underlying pathogenesis resides within the support cells of the retina, the retinal pigment epithelium (RPE).

Cells were cultured in human foetal RPE medium [30] where, within 13 days, they formed a pigmented monolayer with characteristic RPE cobblestone appearance similar to that observed in human post-mortem RPE sheets and HESC - derived RPE cells [9](Fig.Cells were cultured in human foetal RPE medium [30] where, within 13 days, they formed a pigmented monolayer with characteristic RPE cobblestone appearance similar to that observed in human post-mortem RPE sheets and HESC - derived RPE cells [9](Fig.cells [9](Fig. 1B).

To further examine the morphology of cells and the localization of protein expression within the retina, immunohistochemical staining of both paraffin and OCT retinal sections was performed with the following antibodies (Table S1): human cone arrestin (for cone photoreceptors), rhodopsin (for rod photoreceptors), RPE65 (for the retinal pigment epithelium, RPE), glial fibrillary acidic protein (GFAP, for astrocytes and Müller cells), glutamine synthetase (for Müller cells) and G0alpha (for ON bipolar cells).
