Fig. 4. Maternal expression of Nasonia hunchback. (A) Nasonia
hunchback mRNA is loaded from the nurse cells (Nc) of which there
are 15, as in Drosophila into the maturing oocyte (Oc). The
non-staining cells surrounding the oocyte are the follicle cells (Fc). (B)
Negative-control staining using a sense Nasonia hunchback probe.
