Figure 2. Diagram illustrating the orientation of the transverse and sagittal sections in subsequent figures. Lateral view (A) and ventral view (B) of a stage-39 embryo. The black lines indicate the level of the transverse (A) and sagittal (B) sections. The diagrams are modified from Nieuwkoop and Faber (1967). C, D: Higher magnification of the two regions boxed in A and B. The position of the developing OFT and AV canal is indicated in blue and red, respectively. E, F: Schematic representation of the H-E stained sections as shown in Figure 3A and G, respectively, illustrating the topography of the tissues as they relate to cardiac cushion formation. The positions of future OFT (blue) and AV (red) cushions are highlighted. AA, aortic artery; AVC, atrioventricular canal; CJ, cardiac jelly; E, endocardium; EMT, site of epithelial-to-mesenchymal transformation; G, gut; L, liver; M, myocardium; OFT, outflow tract; PE, pharyngeal endoderm; PM, pharyngeal mesoderm; V, ventricle.
