General Information
Term fat body ID (Ontology) FBbt:00005066 (Fly Anatomy)
Definition Collective term for the masses and sheets of adipose tissue that are distributed throughout the organism's body. The adult and larval fat bodies are composed of different cell lineages, but perform the same main function of fat storage (Musselman and Kuhnlein, 2018).[ FlyBase:FBrf0031020 FlyBase:FBrf0064793 FlyBase:FBrf0238315 ]
