All terms in UBERON

Label Id Description
prechordal plate UBERON_0003063 [A horseshoe-shaped thickening of the endoderm at the cranial (rostral) end of the primitive streak formed by the involution of Spemann's organizer cells which, together with the notochord, induces the formation of the neural plate from the overlying ectodermal cells and contributes mesodermal type cells to the surrounding tissue.]
pharyngeal arch 2 UBERON_0003066 [The second pharyngeal arch will form the hyoid apparatus. The cranial neural crest cells that populate the second pharyngeal arch emerge primarily from rhombomere 4 and will form skeletal elements.]
purine nucleoside triphosphate CHEBI_26393
regulation of secondary metabolite biosynthetic process GO_1900376 [Any process that modulates the frequency, rate or extent of secondary metabolite biosynthetic process.]
ciliary marginal zone UBERON_0003065 [Region at the periphery of the retina where retinal stem cells are located. After 60 hpf, the CMZ is the source of most retinal growth.[Wehman et al, 2005].]
negative regulation of secondary metabolite biosynthetic process GO_1900377 [Any process that stops, prevents or reduces the frequency, rate or extent of secondary metabolite biosynthetic process.]
pronephric duct UBERON_0003060 [In mammals, the pronephric duct is the predecessor of the Wolffian duct[WP].]
positive regulation of secondary metabolite biosynthetic process GO_1900378 [Any process that activates or increases the frequency, rate or extent of secondary metabolite biosynthetic process.]
purine nucleoside diphosphate CHEBI_26391
primitive knot UBERON_0003062 [Organizer for gastrulation in vertebrates. The primitive knot starts as a regional knot of cells that forms on the blastodisc immediately anterior to where the outer layer of cells will begin to migrate inwards - an area known as the primitive streak. Posterior to the node is the primitive pit, where the cells of the epiblast (the upper layer of embryonic cells) initially begin to invaginate. This invagination expands posteriorly into the primitive groove as the cells layers continue to move into the space between the embryonic cells and the yolk. This differentiates the embryo into the germ layers - endoderm, mesoderm, and ectoderm. The primitive knot migrates posteriorly as gastrulation proceeds, eventually being absorbed into the tail bud.[WP]. the regional thickening of cells at the rostral tip of the vertebrate primitive streak through which gastrulating cells migrate anteriorally to form tissues in the future head and neck; this region organizes the formation of the three embryonic layers and establishes the longitudinal axis and the polarity of the embryo[MP].]
axial mesoderm UBERON_0003068 [The axial mesoderm includes the prechordal mesoderm and the chordamesoderm. It gives rise to the prechordal plate and to the notochord.]
otic placode UBERON_0003069 [A cranial placode which, once specified, invaginates to form an otic cup, which eventually separates from the surface ectoderm to form the otic vesicle or otocyst, a rounded structure without appar- ent polarity. As the otic placode invaginates into a cup neuroblasts delaminate from the anterior ventral aspect of the otic epithelium to give rise to neurons of the vestibulocochlear (statoacoustic) ganglion of cranial nerve VIII[NBK].]
EC 3.1.3.1 (alkaline phosphatase) inhibitor CHEBI_63332 [An EC 3.1.3.* (phosphoric monoester hydrolase) inhibitor that interferes with the action of alkaline phosphatase (EC 3.1.3.1).]
mesonephric duct UBERON_0003074 [Paired organ that connects the primitive kidney Wolffian body (or mesonephros) to the cloaca and serves as the anlage for certain male reproductive organs. the Wolffian duct is what remains of the pronephric duct after the atrophy of the pronephros[WP]. In Zebrafish: Duct of the adult kidney (mesonephros), present bilaterally ventral to the somites and leading to the cloacal chamber[ZFA].]
paraxial mesoderm UBERON_0003077 [The paraxial mesoderm is the mesoderm located bilaterally adjacent to the notochord and neural tube[GO].]
posterior neural tube UBERON_0003076
eye primordium UBERON_0003071 [Portion of tissue that is part of the anterior neural keel and will form the optic vesicle[ZFA]. A paired ectodermal placode that becomes invaginated to form the embryonic lens vesicles.]
trigeminal placode complex UBERON_0003070 [A neurogenic placode that arises at the level of the midbrain-hindbrain boundary and develops into a trigeminal ganglion.]
lens placode UBERON_0003073 [A thickened portion of ectoderm which serves as the precursor to the lens. SOX2 and Pou2f1 are involved in its development[WP].]
obsolete predominantly gray regional part of ventral posterior nucleus UBERON_0029681
