Fig. 7. Distribution of NrxIV, Con and Nrg in the FCE. All pictures show
antibody staining of wild-type ovaries. (A,B) NrxIV (red)
gradually concentrates at the basal side of the lateral membrane of follicle
cells during development. (C-E) Cont (red) can bee seen in a punctate
staining during early and mid-oogenesis (D). In older egg chambers (E), Cont
concentrates apicolaterally. (F) Nrg (red) is expressed in the lateral
cell membrane. (G) Surface views of the FCE showing NrxIV (green,
G'), Cont (red, G'') and Nrg (blue, G'''). All three proteins
co-localize at tricell junctions. Green indicates actin in A-D,F.
(B',D',E') Red channel only.
