General Information
Term fat cell ID (Ontology) FBbt:00046052 (Fly Anatomy)
Definition A cell that is the principal cell type of the fat body and is filled with lipid droplets.[ FlyBase:FBrf0017184 FlyBase:FBrf0238315 ]
Also Known As "adipocyte" ; "adipose cell" ; "fat body cell"
Comment Adult and larval fat cells are specifically marked by Lsp2 expression, with greater expression at the larval stage (Lazareva et al., 2007 - FBrf0192478; Chintapalli et al., 2007 - FBrf0200485; Armstrong et al., 2014 - FBrf0226784). There is also relatively high expression of ppl and apollp in adult and larval fat cells (Colombani et al., 2003 - FBrf0161991; Chintapalli et al., 2007; Brankatschk and Eaton, 2010 - FBrf0211445).
