Expression of chinmoUAS.fl under the control of Scer\GAL4A3.eya leads to following changes in the testes: an increase in the number of undifferentiated germ and cyst cells throughout the testes (bright DAPI labelled cells, although with normal germ cell ensheathment (DE-cad staining)); most somatic cells show characteristics of cyst stem cells/early cyst cells exhibiting high levels of Tj and Zfh1, but low levels of Eya; most germ cells retain germline stem cells/gonioblasts characteristics, with germ cells residing far from the Hub exhibit high esg levels and individual cells/pairs of cells containing fusomes and not expressing Bam; and excess germ cells and somatic cells often undergo mitosis as single cells when compared to controls.
Expression of chinmoUAS.fl under the control of Scer\GAL4VP16.nos.UTR does not lead to expansion of germline stem cells (Vasa staining) or cyst stem cells (Tj staining) when compared to controls.
chinmoUAS.fl rescues chinmoST
Expression of chinmoScer\UAS.fl under the control of Scer\GAL4C587 rescues the somatic cell defects of chinmoST/chinmoST mutant testes.
Expression of chinmoScer\UAS.fl, under the control of Scer\GAL4OK107 grossly rescues the phenotypes characteristic of chinmo1 mutant mushroom body neuroblast clones.
