Allantoic epithelium and epithelium from different levels of the digestive tube of the guail embryo were grafted into chick embryo splanchnopleure so that these epitheliums would come into contact with the mesoderm of the developing host digestive tube at a variety of levels. Under these conditions, the allantoic epithelium develops into an epithelium corresponding to the level of the digestive tube at which it was grafted. By contrast, the presumptive fate of epithelium from the small intestine is not modified by the mesenchyme with which it becomes associated. Mesenchyme from the small intestine, on the other hand, always dictates the type of differentiation in epithelial grafts from other levels of the digestive tube.
将鹌鹑胚胎的尿囊上皮和来自消化管不同水平的上皮移植到鸡胚脏壁中胚层，以使这些上皮在不同水平与发育中的宿主消化管中胚层接触。在这些条件下，尿囊上皮发育成与其移植部位相对应的消化管水平的上皮。相比之下，小肠上皮的预定命运不会因与之相关的间充质而改变。另一方面，小肠间充质总是决定来自消化管其他水平的上皮移植物的分化类型。
