It divides during larval stages to form clusters called midgut imaginal islands. Its first division is asymmetric and produces a peripheral cell, subsequent divisions generate more adult midgut progenitor cells (Mathur et al., 2010). fly_anatomy.ontology midgut histoblast These cells can be identified by their expression of escargot (Jiang and Edgar, 2009).
