Formation of furrows in the cytoplasm between nuclei during cell cycles in embryos in the syncytial blastoderm stage. An example of this process is found in Drosophila melanogaster. Movement of the anterior ectoderm to the interior of the embryo. The spreading of the amnioserosa from its compressed state to cover the whole of the dorsal surface. Initiating in the thorax and spreading posteriorly, it is accompanied by the transition from a parasegmental to segmental division of the embryo. The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally. Maintenance of the amnioserosa, an epithelium that occupies a hole in the embryonic dorsal epidermis. The directed movement of nuclei within the syncytial embryo of insects. These precise temporal and spatial patterns of nuclear movement are coordinated with mitotic divisons and are required during blastoderm formation to reposition dividing nuclei from the interior of the syncytial embryo to the cortex. 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 whose specific outcome is the progression of the embryo over time, from zygote formation through syncytial blastoderm to the hatching of the first instar larva. An example of this process is found in Drosophila melanogaster. The process whereby a relatively unspecialized cell acquires the specialized features of a garland cell, a small group of nephrocytes which take up waste materials from the hemolymph by endocytosis. The process whose specific outcome is the progression of an embryo over time, from zygote formation until the end of the embryonic life stage. The end of the embryonic life stage is organism-specific and may be somewhat arbitrary; for mammals it is usually considered to be birth, for insects the hatching of the first instar larva from the eggshell.
