Fig. 3. Localization of XSOX7 RNA in stage 27 embryos. (Panel A) An embryo stained for XSOX7 RNA (‘XSOX7’) is compared to an embryo stained for X-msr RNA (‘X-msr’). There is strong XSOX7 staining in the posterior cardinal veins (pcv), hindbrain (hb), aorotic arch (aa), vitilline veins (vv), and the procardiac tube (pct). In transversally sectioned embryos stained for X-msr (B) or XSOX7 (C) the staining of the posterior cardinal veins by both probes is clearly visible. The XSOX7 probe also stains epidermal ciliated cells (cc) and the dorsal aspect of the neural tube (dnt). (D) A transverse section through the hindbrain region reveals XSOX7 staining in the endocardium of the procardiac tube, the aortic arch and the hindbrain. |
