为了建立一个参考系统来评估正在进行的斑马鱼上皮-间充质相互作用调控牙齿发育的体外和原位杂交实验，我们在这里描述了咽齿的发生，以及受精后14天牙齿的组织发育，使用了连续的半薄切片，手工和计算机辅助重建和透射电子显微镜。斑马鱼幼体的牙齿图案是从孵化前不久开始以可预测的、两侧对称的方式产生的。与牙齿发育和结构有关的特征与幼体标本和其他硬骨鱼所描述的特征有很大不同。与鲤鱼情况相关的特殊特征包括复杂的上皮连通性和牙齿的附着方式。
In order to build a reference system to assess ongoing in vitro and in situ hybridisation experiments on epithelial-mesenchymal interactions governing odontogenesis in the zebrafish, we describe here the generation of the pharyngeal dentition, and the histological development of teeth up to fourteen days post-fertilization, using serial semithin sections, handmade and computer-assisted reconstructions and transmission electron microscopy. The tooth pattern in larval zebrafish is generated in a predictable, and bilaterally symmetrical manner from shortly before hatching onwards. Characteristics related to tooth development and structure differ considerably from those seen in juvenile specimens and those described for other bony fishes. Particular features related to the cyprinid condition include the complex epithelial connectivity and the mode of attachment of the teeth.
