Inx4 is localized to membrane plaques in germ-line cells and seems to interact with Inx2 in follicle cells. A, B: Inx4-plaques (arrows in A (tangential section) and B (median section), stage 6, LSM) were detected between each follicle cell and the underlying oocyte and nurse cells, respectively. Continuous staining was found at the nurse-cell membranes (arrowhead in B). C: Inx4-plaques (black arrowheads, stage 10b, WFF) are located between nurse cells and the centripetally migrating follicle cells. D: Inx2 in follicle-cell membranes (green, AInx2GP-CL) and Inx4 in nurse-cell membranes (red, AInx4Rb-CT) are in close vicinity (arrowheads, stage 8, LSM) and seem to interact. Beginning with stage 8, only Inx2 is present between oocyte and follicle cells (arrow). For further abbreviations, see legend to Fig. 1.
