MLC1v promoter activity observed in MLC1v::EGFP transgenic frog hearts. A-E: The heart of an 80 day old, recently-metamorphosed froglet. Terminal anaesthesia was used to stop the animal's heart beat and its pericardium removed by dissection to reveal the cardiac chambers. The atria are filled with blood, ventricle part-filled. A, B: Bright-, and dark field views of the entire heart. C-E: High magnification views of the single ventricle (C), left atrium (D), and right atrium and proximal outflow tract (E). F-H: The heart, dissected from a 39 week old juvenile frog, showing bright EGFP fluorescence in the ventricle and some myocardial fibres of the atrial chambers (F). High magnification views of the left atrium (G) and proximal outflow tract (H). A coronary vessel in the outflow tract can be seen as a dark silhouette in (H). Distinct MLC1v-expressing myocardial fibre morphologies are observed in the different compartments of the heart. V, ventricle; LA, left atrium; RA, right atrium; OT, outflow tract; CV, coronary vessel. Image created by: Stuart J. Smith, Image published in: Smith SJ et al. (2005) Copyright © 2005.
