FIGURE 1.

Armitage is localized in the Yb body in ovarian somatic cells. Shown is the immunofluorescence costaining of FLAG-Yb (red) and Armi (green) in a 5×FLAG-Yb transgene ovariole (A) and a stage 4 egg chamber (B–E). DNA was labeled with DAPI (blue). Armi was enriched in the nuage (Nu) in nurse cells (NC) and colocalized with Yb in somatic cells in the Yb body (YB). The inset in A is a magnified view of the boxed area in A. GSC, germ line stem cells; SCC, somatic cap cells; FC, follicle cell; Ge, germarium. S2, S3, and S5 designate stage 2, 3, and 5 egg chambers, respectively.
