General Information
Term adult midgut interstitial cell ID (Ontology) FBbt:00110909 (Fly Anatomy)
Definition Interstitial cell of the adult midgut. It is found in the anterior midgut subregions of region R3 (R3a and R3b, copper cell region), interspersed with copper cells. They have apically localized nuclei, short microvilli in the apical membrane and a broad apical profile. The interstitial cell arches over the apex of the copper cell, forming a narrow channel that connects the apical invagination of the copper cell to the gut lumen. The highly folded area of apicolateral contact between copper and interstitial cells contains smooth septate junctions.[ FlyBase:FBrf0064792 FlyBase:FBrf0139611 FlyBase:FBrf0174753 FlyBase:FBrf0216495 FlyBase:FBrf0221749 ]
