As compared to wild type, RNAi THS-044 chemical information ovarioles are depleted of most eggchambers and also the vitellarium is shortened. In addition, the transition zone among tropharium and vitellarium, which harbours the somatic plug, prooocytes, and prefollicular cells, is severelyaffected (FigB).

Eya is expressed in central prefollicular cells (CPC, yellow outline) and the somatic plug (SP, green outline) (B) Ovarioles dissected at indicated time points just after adult knockdown of TC. A subset of CPC begins to express Eya at reduced levels (border in between high and low expression of Eya in CPCs is marked by the yellow dashed line) (B). At dpi, CPCs occupy a smaller sized location and Eya expression is additional reduced. The somatic plug (SP) appears less condensed and occupies a larger area (C). CPCs expressing lowered amounts of Eya are lost at dpi (D). The terminal phenotype can be observed at dpi. Only a little population of Eya optimistic CPCs is still present and the SP has expanded much more.

Prooocytes will not be longer encapsulated by central prefollicular cells, but remain in the transition zone, resulting in an excess of prooocytes in this region (Figasterisks and arrows in B). Interestingly, while lateral prefollicular cells are essentially present, central prefollicular cell populations are largely absent (see beneath). To further elucidate the functions of TC in early follicle cell specification, we performed adult RNAi and analysed the resulting phenotypes by morphology and Eya staining (Fig.).
