General Information
Term embryonic/larval oenocyte ID (Ontology) FBbt:00001694 (Fly Anatomy)
Definition Embryonic/larval oenocytes are large, polyploid cells whose cytoplasm contains yellowish granules. They are arranged in clusters in abdominal segments 1-7, under the epidermis, to which they are attached by fine elastic cellular extensions. As the animal ages, the number of granules increases and the cells become highly enlarged relative to their neighbors. These cells have been shown to function in the breakdown of stored lipids and may also control feeding behavior (Gutierrez et al., 2007). These cells degenerate during late pupal stages.[ FlyBase:FBrf0007734 FlyBase:FBrf0192579 ]
Also Known As"larval oenocyte"
