Gastrulation is the stage in the early embryonic development of most animals, during which the blastula (a single-layered hollow sphere of cells), or in mammals, the blastocyst, is reorganized into a two-layered or three-layered embryo known as the gastrula. [1]

原肠胚 （gastrula）是 动物 胚胎發育 的一个阶段。 当细胞分裂成为 囊胚 之后，会经过一段称为原肠形成的型态发生过程，之后形成 原肠胚。

Gastrula, early multicellular embryo, composed of two or more germinal layers of cells from which the various organs later derive. The gastrula develops from the hollow, single-layered ball of cells called a blastula which itself is the product of the repeated cell division, or cleavage, of a

打卡继续，今天打卡这篇单细胞解读gastrulation发育的文章，19年的nature.为什么关注gastrulation：across the animal kingdom, gastrulation represents a key developmental event during which embryonic pluri…

During gastrulation, the germ layers of an embryo are formed and the body plan of the mature organism is established. Movements on a massive scale allow cells to establish great complexity from a very simple starting form.

2021年2月9日 · Gastrulation is a process of cellular rearrangement which involves migration, invagination and differentiation of the epiblast. It is largely controlled and orchestrated by the primitive streak. The primitive streak is a groove in the midline of the epiblast which appears during the third week.

2024年4月23日 · Gastrulation orchestrates the transformation of the bilaminar embryonic disc within the blastula into a complex multi-dimensional structure known as the gastrula. 1 This …

2017年4月27日 · Gastrulation is the process during embryonic development that changes the embryo from a blastula with a single layer of cells to a gastrula containing multiple layers of cells. Gastrulation typically involves the blastula folding in upon itself or …

The term gastrulation means the formation of gut (Greek, gastrula = belly), but has now a more broad sense to to describe the formation of the trilaminar embryo. The epiblast layer, consisting of totipotential cells, derives all 3 embryo layers: ectoderm, mesoderm and endoderm.

2025年1月10日 · What Is Gastrulation? Gastrulation is a crucial process in early embryonic development, involving the formation of three germ layers: ectoderm, mesoderm, and endoderm. During gastrulation, the blastula reorganizes into a gastrula, setting the stage for subsequent tissue and organ formation.
