Fig. 6. Nasonia Hunchback in serosa and nervous system of wild-type
embryos. (A) A dorsal stripe of mRNA expression initiates shortly before
gastrulation. (B) Protein expression in the nuclei of the developing serosa,
soon after germ-band extension. (C,D) Continued protein expression in the
serosa as it begins to expand to envelop the entire embryo. (E) Protein
expression in the nervous system, seen here during head involution. (F)
