FIG. 6. Early vasculature in Xenopus. Ventral view of a double-labelled stage 46 Xenopus embryo (red, anti-cardiac tropon in T (CT3); green, anti-type VI collagen). Image represents 45 optical sections through the embryo, each 10 um thick, digitally merged and colored. The first three branches on the left side of the paired aortic arches are easily distinguished with the antibody to type VI collagen, as are all chambers and the truncus arteriosus with the antibody to cardiac troponin T. Scale bar, 100 um |
