外胚层

But on the other hand, they have contacts all know, there is no long teeth really rare (apart from a very small number of so-called "congenital ectodermal dysplasia," outside of the case).

但是反观就们所接触、所认识的所有人，没有长牙的真的很少见(除了非常少数所谓&先天性外胚层发育不良&的病例以外)。

Inductive interactions mediated by the Msx genes are essential for normal craniofacial, limb and ectodermal organ morphogenesis, and are also essential to survival in mice, as manifested by the phenotypic abnormalities shown in knockout mice and in humans.

基因敲除鼠和人类的畸形表现型的研究显示，Msx基因介导的诱导组织间的相互作用，对正常颅颌面、肢体和外胚层器官的形态发生至关重要。

Yet in many vertebrate groups, teeth are not restricted only to the oral cavity, but extend posteriorly as pharyngeal teeth that could be derived either directly from the endodermal epithelium, or from the ectodermal epithelium that reached this location through the mouth or through the pharyngeal slits.

但在很多脊椎动物里牙齿的发育不仅只有上述来源，还有向后延伸形成的咽部牙齿，可能由内胚层上皮或经由口腔或口咽裂至此部位的外胚层上皮形成。

However, when the oropharyngeal membrane, which forms a sharp ecto/endodermal border, is broken, the fate of these cells is poorly known.

但当作为外胚层和内胚层界限的口咽膜破裂后这些牙齿形成细胞的发育知之甚少。
