F IG. 7. Expression of troponin 1c in lithium-treated embryos, (A) The heart in a stage 28/30 control embryo, Note that it has already formed a simple tube at the ventral midline. (B) A DAI 8 embryo that has an enlarged heart region. Cardiac tissue is absent on the dorsal side of the embryo and has not fused at the ventral midline. (C) A top view of a DAI 9 embryo showing the distribution of heart tissue (arrowheads). Although not visible in its entirety in this view, the heart forms a ring that could be detected around the entire circumference with the exception of a gap (g) on the dorsal side. The heart tissue is just beneath the surface, indicating that it has not involuted. (D) A stage 38 control embryo with the heart undergoing looping and deformations that result in the final morphology. (E) A DAI 9 embryo viewed from the side. The heart now appears radial and is moving to the final location at the center of the embryo. The timing of this movement corresponds to the normal looping and folding events, rather than migration to the ventral midline. (F) A stage 38 DAI 8 embryo with an almost radial heart. The heart has begun to move to the center of the embryo but the most dorsal side of the embryo (arrow) is still thin. Image published in: Drysdale TA et al. (1994) Copyright © 1994.
