General Information
Term midgut enterocyte ID (Ontology) FBbt:00047177 (Fly Anatomy)
Definition Specialized epithelial cell of the midgut. A large, polyploid, cuboidal or low-columnar epithelial cell with its nucleus in the middle and a mass of microvilli (brush border) on its apical surface. On its basal side, extensive infoldings of the plasma membrane form a labyrinth which fills the lower half of the cell. It is attached to adjacent enterocytes by smooth septate junctions.[ FlyBase:FBrf0007735 FlyBase:FBrf0139657 FlyBase:FBrf0191251 ]
Also Known As "midgut EC"
Comment Can be identified in adults and larvae based on expression of nubbin, Myosin31DF (Sawyer et al., 2017) and mex1 (Phillips and Thomas, 2006 - FBrf0190960; Chen et al., 2014 - FBrf0226781).
