色素细胞能使鱼改变颜色。鱼类的颜色变化可以分为两类：一类是生理性颜色变化，这是由于色素细胞的快速运动反应，另一类是形态学颜色变化，这是由于色素细胞的形态和密度的变化。鱼类对特定背景的长期适应可以作为形态颜色变化的一般线索，并且从世纪开始就已经进行了研究。虽然鱼类色素细胞的运动机制及其控制正在阐明，但尚不清楚色素细胞如何改变其密度以及是什么控制了形态学颜色的变化。近年来，色素细胞，特别是黑色素细胞，已被证明是分化和凋亡的影响下，调节运动反应的因素。这些因素很可能利用共同的细胞内信号通路，部分用于调节两种类型的颜色变化。在这篇文章中，在简要回顾了早期研究的历史，最近的研究结果进行了讨论有关增加或减少色素细胞，并在其形态的变化。最后，形态颜色的变化进行了讨论，作为生理现象参与的色素细胞的分化和凋亡之间的平衡。
Pigment cells enable fish to change their coloration. It has been recognized that fish color changes can be divided into two categories; one is a physiological color change, which is attributed to rapid motile responses of chromatophores, and the other is a morphological color change, which results from changes in the morphology and density of chromatophores. Long-term adaptation of fish to a certain background can be a general cue to morphological color changes, and has been studied from the beginning of the 19th century. Although the motile mechanism and its control in fish chromatophores are now being elucidated, it is not yet clear how chromatophores change their density and what controls morphological color changes. In recent years, chromatophores, especially melanophores, have been shown to differentiate and to die by apoptosis under the influence of factors that regulate motile responses. Those factors are likely to utilize common intracellular signaling pathways used in part to regulate both types of color changes. In this article, after briefly reviewing the history of early studies, recent findings are discussed relevant to increases or decreases in chromatophores, and changes in their morphology. Finally, morphological color changes are discussed as physiological phenomena involved in the balance between differentiation and apoptosis of chromatophores.
