胚胎的早期发育 meaning in English
early development of the embryo
Examples
- Alterations in glycosylation have been proposed to participate in cell adhesion , receptor activation , cell differentiation and tissue morphogenesis . because the early embryo is composed of cells that must adhere to other embryonic cells , it seems likely that glycans modulating this adhesion would have been indispensable for early development . genetic elimination or partial abrogation of expression of some major classes of glycans , such as n - glycans , glycosphingolipids , hyaluronan and sialic acids , has been shown to be lethal during murine embryogenesis
胚胎发育过程中伴随着细胞表面糖链表达水平及结构的改变，研究表明这些改变参与介导了胚胎细胞之间的粘附联系，因此，糖链对于胚胎正常发育是必须的，一些糖链结构(如n -连接糖链，糖鞘脂，透明质酸，唾液酸等)的表达缺失能导致小鼠死亡于胚胎的早期发育阶段。
