Abstract MCH was originally discovered as a cyclic neuropeptide in the chum salmon pituitary. MCH is secreted from the pituitary into the circulation, and is responsible for aggregating melanin granules in teleost fishes. Mammalian MCH was subsequently identified in the rat hypothalamus.

IT has been suggested recently1 that 5 : 6: 5â:6â-tetrahydroxy-indigo (I), or a quinone or semi-quinone derived from it, is an important constituent of melanin, the black pigment produced by the oxidation of tyrosine and 3 : 4-dihydroxyphenylalanine2.

Extra‐cutaneous melanocytes derive from either the neural crest, the outer wall of the optic cup, or the cranial neural tube. Those of neural crest origin reach most bodily regions, and may give rise to primary melanoma in various tissues. The Kupffer cell produces a form of melanin, but is hardly a melanocyte.
