Fig. 3. Tbx1 gene expression and Cre recombination in embryos at E9. X-gal-stained wholemount embryos (A-F) and coronal sections through the pharynx of the same embryos (A'-F'). (A,A') Tbx1^+/–; (B-B'') Nkx2.5^Cre/+; R26R; (C,C') Mesp1^Cre/+; R26R; (D,D') Foxg1^Cre/+; R26R; (E,E') TgFgf15Cre; R26R (E9.5 embryo); (F,F') Hoxa3^Cre/+; R26R. Position of the sections in B' and B'' are indicated in B. se, surface ectoderm; pm, pharyngeal mesoderm; pe, pharyngeal endoderm; p, pharynx; II, III, second and third pharyngeal arches. Scale bars: 200 µm.
