✦ Synopsis

Abstract

The common goldfish depigments its larval choroidal melanophores as well as the skin melanophores for about two to three months following hatching. Thereafter it begins to show a characteristic xanthic coloration. This depigmentation is under the control of depigmentation genes Dp~1~ and Dp~2~. The larval choroidal melanophores of the common goldfish were cultured in vitro for more than four months without showing any sign of depigmentation. During the same period the skin and choroidal melanophores in the control fish had completely depigmented. The addition of thyroid hormone and ACTH to the culture medium had no effect on depigmentation. The mechanisms of depigmentation in the goldfish are discussed.

The use of in vitro gene reporter assays is becoming increasingly widespread in biology and particularly in drug metabolism, where the need for rapid screening of novel compounds is a driving factor. There is, however, little standardization of technique in the control of such assays, nor in the int
