Under control conditions, the adulthood-only expression of HScer\UAS.cUa under the control of Scer\GAL4esg-NP7397 (and Gal80[ts], for the temporal regulation of expression) leads to a significant increase in the adult posterior midgut mitotic index in females only, as compared to controls.
Scer\GAL4Dl-NP0677-mediated expression increases the number of intestinal stem cells in the adult midgut.
Expression of HScer\UAS.cUa under the control of Scer\GAL4tub.PU in intestinal stem cell (ISC) clones results in a large increase in clone size compared to wild-type clones and results in additional, small ISC-like cells.
