Drives expression in histoblasts and histoblast nests, in enteroblasts, and in intestinal stem cells.
drives expression in abdominal histoblast nests and histoblasts, but not in cuticular larval epidermal cells.
expression is observed in 36% of small cells that occupy a basal position within the adult midgut epithelium.
Expression in second instar leg discs is excluded from the distal-most regions. Third instar expression is observed in the proximal region of the leg discs.
