在卵内用活体染料DiI标记最尾体节后面的各种内胚层部位，并在再孵育2或3天后分析标记的内胚层的命运。该区域的内胚层在空肠尾侧和卵黄囊后成为肠上皮。消化管背侧部细胞所占的区域位于轴向和近轴中胚层覆盖区域的中心周围，腹侧消化区位于外侧，有相当大的重叠，被卵黄囊区包围。在后消化管的形成过程中，内胚层向前向后延伸到相当大的程度。对泄殖腔有贡献的细胞和在大肠中产生后代的细胞占据了菱形窦中心后部的类似区域，这些区域包括在更向前延伸的回肠前区域中。空肠前细胞通常位于比回肠前细胞更靠前的位置。前尿囊细胞位于后原条周围相当小的区域内。
Various endodermal sites posterior to the caudal‐most somite were marked in ovo with the vital dye DiI, and the fate of marked endoderm was analyzed after 2 or 3 days’ reincubation. The endoderm in this area became gut epithelium posterior to the caudal jejunum and yolk sac. The area occupied by the cells that were to contribute to the dorsal part of the digestive tube lay centrally around the area overlaid by axial and paraxial mesoderm, with the preventral digestive area lying outside with considerable overlapping, which was surrounded by the preyolk sac area. During the formation of the posterior digestive tube, the endoderm was elongated anteroposteriorly to a considerable degree. Cells that contributed to the cloaca and those that produced descendants in the large intestine occupied similar areas posterior to the center of the sinus rhomboidalis, which were included in the pre‐ileal area extending more anteriorly. Prejejunal cells generally localized in a more anterior position than pre‐ileal cells. Pre‐allantoic cells were located in a rather small area around the posterior primitive streak.
