Name: melanocyte
Synonyms: melanophore
Definition: A pigment cell derived from the neural crest. Contains melanin-filled pigment granules, which gives a brown to black appearance.
Ontology: Anatomy Ontology [ZFA:0009091]
Name: pigment granule
Synonyms:
Definition: A small, subcellular membrane-bounded vesicle containing pigment and/or pigment precursor molecules. Pigment granule biogenesis is poorly understood, as pigment granules are derived from multiple sources including the endoplasmic reticulum, coated vesicles, lysosomes, and endosomes.
