General Information
Term ectoderm ID (Ontology) FBbt:00000111 (Fly Anatomy)
Definition Outermost germ layer of the embryo (Campos-Ortega and Hartenstein, 1997). It is formed from the ectoderm anlage, which includes the cells of the cellular blastoderm monolayer that do not invaginate during gastrulation (Campos-Ortega and Hartenstein, 1997).[ FlyBase:FBrf0089570 FlyBase:FBrf0155831 FlyBase:FBrf0244630 ]
