Zebrafish have distinctive black stripes and yellow interstripes that form owing to the interaction of different pigment cells. We present a two-population agent-based model for the development and regeneration of these stripes and interstripes informed by recent experimental results. Our model describes stripe pattern formation, laser ablation and mutations. We find that fish growth shortens the necessary scale for long-range interactions and that iridophores, a third type of pigment cell, help align stripes and interstripes.
斑马鱼具有独特的黑色条纹和黄色条纹间隔,这些是由不同色素细胞相互作用形成的。我们基于最近的实验结果,提出了一个基于双种群智能体的模型,用于这些条纹和条纹间隔的发育与再生。我们的模型描述了条纹图案的形成、激光消融和突变。我们发现鱼类生长缩短了长程相互作用所需的尺度,并且虹彩细胞(第三种色素细胞类型)有助于使条纹和条纹间隔对齐。
