hypoblast

GFP expression started during gastrulation in the axial hypoblast layer .

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；

The proembryo from zygotic cell divisions may be divided into three parts : proper , hypoblast and suspensor .

玉米合子细胞分裂形成的原胚分为胚柄、基与胚体三部分。

The trumpet_shaped hypoblast was a transitional region situated between the suspensor and the embryo proper .

胚基为胚柄和胚体之间的过渡区，呈喇叭状，胚基与胚柄不能等同。

Four types of the of grafts from the organizer area were transplanted into host embryos to see if the epiblast or hypoblast of the organizer area had an ability to induce a secondary embryo .

并将组织者区域的细胞移植到宿主胚胎中，验证其诱导次级胚胎的能力。

As to the hypoblast there is a growth belt , which promotes elongation of the hypoblast . Eventually the upper portion of the hypoblast contributes to the formation of the coleorhiza and the remainder dries up , sticking to the end of the coleorhiza .

胚基具有生长带，纵向伸长长度大，胚基的上部参与形成胚根鞘，其余部分干缩后附在胚根鞘末端。
