The migration of inner marginal cells was studied in the Ambystoma gastrula, using scanning electron micrography and time-lapse cinemicrography. Scanning electron micrographs of gastrulae which were fixed while intact revealed that the migrating cells have flattened lamellipodia at their anterior end and a rounded cell body, which can sometimes be seen to be attached to a neighbouring cell by a slender posterior process. Films of opened gastrulae showed actively moving cells, with the same features described above. Details of their movements are reported and discussed in relation to the mechanism of gastrulation.
利用扫描电子显微镜和延时显微电影摄影技术，对美西螈原肠胚中内边缘细胞的迁移进行了研究。完整固定的原肠胚的扫描电子显微镜图像显示，迁移细胞的前端有扁平的片状伪足和圆形的细胞体，有时可以看到细胞体通过细长的后端突起与相邻细胞相连。打开的原肠胚的影片显示细胞在活跃移动，具有上述相同特征。本文报告并讨论了它们运动的细节及其与原肠胚形成机制的关系。
