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

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

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 chemical reactions and pathways resulting in the formation of 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 accumulation of pigment in an organism, tissue or cell, either by increased deposition or by increased number of cells.

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 of neuroblast proliferation.

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 whose specific outcome is the progression of the epidermis over time, from its formation to the mature structure. The epidermis is the outer epithelial layer of an animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species.

The proliferation of neuroblasts in the ventricular zone of the cerebral cortex. The neuronal progenitors of these cells will migrate radially.

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

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

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

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

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

The developmental process that results in the deposition of coloring matter in an organism, tissue or cell.

The process whose specific outcome is the progression of the cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate.

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.

The lipid bilayer surrounding a melanosome.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The lipid bilayer surrounding a melanosome.

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

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The lipid bilayer surrounding an endosome.

The lipid bilayer surrounding an endosome.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The lipid bilayer surrounding a clathrin-coated endocytic vesicle.

The lipid bilayer surrounding a clathrin-coated endocytic vesicle.

The lipid bilayer surrounding a melanosome.
