斑马鱼的有序色素模式是研究动物空间模式形成的一个很好的模型系统。最近的分子遗传学研究表明，色素细胞之间的相互作用在图案形成中起着重要作用。在本研究中，我们进行了比较透射电子显微镜的色素细胞，以澄清组织中的色素细胞的结构相互作用，和没有条纹图案。在图案化的组织中，色素细胞呈单细胞厚的片状分布。图纸的层顺序始终严格保持。在没有条纹图案的组织中，层序经常被打乱，或者细胞以散在的、双层的或堆积的方式分布。我们的观察表明，控制色素细胞的垂直顺序的潜在机制与控制条纹图案的机制有关。
The orderly pigment pattern of zebrafish (Danio rerio) is a good model system for studying how spatial patterns form in animals. Recent molecular genetic studies have shown that interactions between the pigment cells play major roles in pattern formation. In the present study, we performed comparative transmission electron microscopy of pigment cells, in order to clarify the structural interactions of pigment cells in tissues with and without a striped pattern. In patterned tissues, pigment cells were distributed as a one-cell-thick sheet. The layer order of the sheets is always kept strictly. In tissues without a striped pattern, the layer order was often disturbed or the cells were distributed in a scattered, double-sheeted, or an accumulated pile. Our observations suggest that the underlying mechanism that controls the vertical order of the pigment cells is related to that controlling the stripe pattern.
