MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.
Term:abnormal tooth placode morphology
go back to main search page
Accession:MP:0030510 term browser browse the term
Definition:any structural anomaly of the local thickening that is formed within the primary dental lamina and grows into a solid epithelial tooth bud that invades the underlying mesenchyme; the placodes consist of thickened epithelium and underlying neural crest derived mesenchyme, and they function as the first signaling centers of the tooth
Comment:The term placode has not been universally adopted in the field of tooth development research; in mouse, stages prior to bud (E11–E12.5) have often been collectively referred to as the epithelial thickening, dental lamina, or simply initiation stage {xref="PMID:24487243"}
Synonyms:exact_synonym: abnormal dental anlage morphology;   abnormal dental placode morphology;   abnormal dental primordium morphology;   abnormal odontogenic placode morphology;   abnormal tooth anlage morphology;   abnormal tooth primordium morphology
