Fig. 8. Changes in the ARH-like transcript during A. aegypti egg chamber development. Whole-mount in situ hybridization analysis of ovaries dissected from previtellogenic (A), 6 hour (B) or 20 hour post-blood-meal (C-F) females. Fixed ovaries were hybridized with antisense AaARH-like (A-D), vitellogenin receptor (VgR; E) or no (F) riboprobe. The purple staining indicates the positioning of mRNA transcripts. Samples in A-D were treated identically and the images obtained under the same conditions. fc, follicle cells; g, germarium; nc, nurse cells; o, oocyte; sf, secondary follicle.
