The prechordal plate is a thickening of the endoderm at the cranial end of the primitive streak formed by the involution of Spemann's organizer cells. The prechordal plate and the notochord induce the formation of the neural plate from the overlying ectodermal cells.</obo_purl:IAO_0000115> <oboinowl_gen:hasOBONamespace>biological_process</oboinowl_gen:hasOBONamespace> <oboinowl_gen:id>GO:0021501</oboinowl_gen:id> <metadata_def:prefLabel>prechordal plate formation</metadata_def:prefLabel> <metadata_def:mappingLoom>prechordalplateformation</metadata_def:mappingLoom> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/GO_0021501"/> <metadata:treeView rdf:resource="http://purl.obolibrary.org/obo/GO_0007399"/> <metadata:obo/part_of rdf:resource="http://purl.obolibrary.org/obo/GO_0007399"/> <obo_purl:RO_0002297 rdf:resource="http://purl.obolibrary.org/obo/UBERON_0003063"/> </owl:Class> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_0021501"> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/GO_0021501"/> </rdf:Description> </rdf:RDF>
