The formation of the ectoderm, mesoderm and endoderm during gastrulation. A complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. The details of gastrulation vary from species to species, but usually result in the formation of the three primary germ layers, ectoderm, mesoderm and endoderm. The process by which the population of cells that make up a mesendoderm undergo directed movement. The mesendoderm is the epithelial tissue that gives rise to both mesoderm and endoderm. The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant. The process by which anatomical structures are generated and organized during the embryonic phase. Morphogenesis pertains to the creation of form. The embryonic phase begins with zygote formation. The end of the embryonic phase is organism-specific. For example, it would be at birth for mammals, larval hatching for insects and seed dormancy in plants. The epithelial to mesenchymal transition process in which a mesodermal cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell as part of the process of gastrulation. The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form. A gastrulation process in which the initial invagination becomes the anus and the mouth forms second. The change in form that occurs when an epithelial cell progresses from it initial formation to its mature state, contributing to the process of gastrulation. A gastrulation process in which the initial invagination becomes the mouth and the anus forms second. The migration of individual cells within the blastocyst to help establish the multi-layered body plan of the organism (gastrulation). For example, the migration of cells from the surface to the interior of the embryo (ingression). The morphogenetic process in which an epithelium narrows along one axis and lengthens in a perpendicular axis usually resulting in the formation of the three primary germ layers, ectoderm, mesoderm and endoderm. Any process that modulates the rate or extent of gastrulation. Gastrulation is the complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. The attachment of one cell to another cell affecting gastrulation.
