General Information
Term adult posterior midgut epithelium ID (Ontology) FBbt:00007036 (Fly Anatomy)
Definition A columnar - cuboidal epithelial monolayer with a brush border consisting predominantly of large polyploid enterocytes tied together by smooth septate junctions. Scattered through this epithelium are clusters of diploid intestinal stem cells and occasional enteroendocrine cells.[ FlyBase:FBrf0007735 FlyBase:FBrf0139657 FlyBase:FBrf0191251 ]
