Pcsk5 expression in the wild-type embryos. Pcsk5 gene expression analysis using in situ hybridization. (a) Lateral view of an E10.5 wild-type embryo and a close up of its pharyngeal arches (a’). Strong staining is visible in the limb bud (lb), presomitic mesoderm (pms), forming (S0) and last formed (S1) somites, and in the pharyngeal arch (black arrowheads in a and a’). Heart (h) is indicated. (b) Lateral and (b’) dorsal views of an E8.5 wild-type embryo showing strong staining only in forming and last formed somites (S0, S1) and a weak expression in presomitic mesoderm (pms) but not in the heart tube (h) or structures surrounding the heart. Head fold (hf) and allantois (al) are indicated
