CROSS-SPECIES ANATOMY - ANNOTATIONS

The Basic subset of the UBERON integrated, cross-species anatomy ontology is downloaded weekly from http://berkeleybop.org/ontologies/uberon/basic.obo. For more information about this ontology see the "About" page on the UBERON website at http://uberon.github.io/about.html.

Definition:The structure of the outer structural layer of the rodent placenta[MP].
Comment:[development-note] "In the absence of direct lineage analysis, it has been assumed, from histological studies and from the continuity of marker gene expression, that the spongiotrophoblast largely derives from the cells of the ectoplacental cone" xsd:string {source="PMID:19829370"}; [structure-note] "Forms a compact layer of non-syncytial cells between the labyrinth and the outer giant cells"; [taxon-note] "restriction to Rodentia may be too strong - we apply it for now as we are inheriting the MP definition"
Synonyms:exact_synonym: spongiotrophoblast layer of placenta
 broad_synonym: spongiotrophoblast
 xref: BTO:0005402;   EMAPA:31876
