The emphasis of this review is on the primitive streak of the chick embryo, collated with such information as is available on the mouse embryo. Little modern work has been published on any reptile primitive streak. The following topics are considered: evolutionary significance; formation of the primitive streak; ingression and de-epithelialisation; the basal lamina; migration from the primitive streak of the endoderm and mesoderm; the role of the extracellular matrix; changes in cell adhesiveness; regression of the primitive streak and its role in body patterning; the primitive streak and induction.
本综述重点关注鸡胚的原条，并与小鼠胚胎的现有信息进行整理对照。关于任何爬行动物原条的现代研究发表得很少。本文考虑了以下主题：进化意义；原条的形成；内陷和去上皮化；基膜；内胚层和中胚层从原条的迁移；细胞外基质的作用；细胞黏附性的变化；原条的退化及其在身体模式形成中的作用；原条与诱导作用。
