General Information
Term midgut imaginal island ID (Ontology) FBbt:00001837 (Fly Anatomy)
Definition A cluster consisting of adult midgut precursor cells and peripheral cells found adjacent to the basement membrane of the larval midgut. These clusters are scattered throughout the larval midgut. They form by division of adult midgut precursor cells during larval stages. The first division is asymmetrical, producing a peripheral cell, which extends its processes around the adult midgut precursor cells (Mathur et al., 2010).[ FlyBase:FBrf0064792 FlyBase:FBrf0209706 ]
