A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a melanosome. A melanosome is a tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored.

The progression of the retinal pigment epithelium over time, from its initial formation to the mature structure. The retinal pigment epithelium is the melanin-containing layer of cells between the retina and the choroid that absorbs scattered and reflected light and removes waste products produced by the photoreceptor cells.

The process in which a relatively unspecialized cell acquires specialized features of a melanocyte.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a melanosome. A melanosome is a tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored.

The accumulation of pigment in an organism, tissue or cell, either by increased deposition or by increased number of cells.

The chemical reactions and pathways involving melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The chemical reactions and pathways resulting in the formation of melanin from other compounds, including tyrosine.

The process in which a relatively unspecialized cell acquires specialized features of a melanocyte.

The chemical reactions and pathways involving acetoacetic acid, 3-oxobutanoic acid; the empirical formula is C4H6O3 or CH3COCH2COOH.

The accumulation of pigment in an organism, tissue or cell, either by increased deposition or by increased number of cells.

Any process that activates or increases the rate or extent of the chemical reactions and pathways resulting in the formation of melanin.

A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a thyroid hormone stimulus.

A tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored. Melanosomes are synthesized in melanocyte cells.
