FIG. 9. Expression of Xenopus Hand1 in the heart tube. Hand1 transcripts were visualised by whole-mount RNA in situ hybridisation
(purple) in embryos at the linear (stage 30) and looped (stage 35) heart tube stages (A and B, respectively). Serial 10-mm transverse sections
were numbered from the beginning of the pericardial cavity and representative examples are shown. At the linear tube stage, staining is
absent from the left myocardial wall (arrowheads) in anterior sections and increasingly from the right myocardial wall in more posterior
sections. In the looped heart, little or no staining is detected in the dorsal wall of the ventricle or the atrial myocardium (arrowheads). 3D
models constructed from these data show the Hand1 expression domain (red) superimposed on a model of the myocardium (opaque). (Note
that some distortion has occurred as a result of the whole-mount procedure, resulting in compression of the heart loop in both AP and DV
axes.) Image published in: Mohun TJ et al. (2000) Copyright © 2000. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
