"The differentiation of endothelial cells from progenitor cells during blood vessel development, and the de novo formation of blood vessels and tubes [goid 1570] [evidence IEA]; The formation of mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo [goid 1756] [evidence IEA]; The process by which the anatomical structures of the neural plate are generated and organized. Morphogenesis pertains to the creation of form. The neural plate is a specialized region of columnar epithelial cells in the dorsal ectoderm that will give rise to nervous system tissue [goid 1839] [evidence IEA]; The last step in the formation of the neural tube, where the paired neural folds are brought together and fuse at the dorsal midline [goid 1843] [evidence IEA]; Any process that modulates the frequency, rate or extent of DNA-dependent transcription [goid 6355] [evidence IEA]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [pmid 8963900] [evidence NAS]; The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult) [goid 7275] [evidence IEA]; The process whose specific outcome is the progression of the mesoderm over time, from its formation to the mature structure. The mesoderm is the middle germ layer that develops into muscle, bone, cartilage, blood and connective tissue [goid 7498] [pmid 8963900] [evidence TAS]; Any process that activates or increases the rate or extent of cell proliferation [goid 8284] [evidence IEA]; The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote [goid 8595] [pmid 8963900] [evidence TAS]; The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form [goid 9653] [evidence IEA]; The process whose specific outcome is the progression of the notochord over time, from its formation to the mature structure. The notochord is a mesoderm-derived structure located ventral of the developing nerve cord. In vertebrates, the notochord serves as a core around which other mesodermal cells form the vertebrae. In the most primitive chordates, which lack vertebrae, the notochord persists as a substitute for a vertebral column [goid 30903] [evidence IEA]; Any process that modulates the frequency, rate or extent of DNA-dependent transcription [goid 6355] [evidence IEA]"
