Figure 4A. NF Stage 35: cardiac troponin T (red), fibrillin (green). Myocardial wall closed and heart tube twisted into an "S" shape. Chambers now distict.

Figure 4C. NF Stage 41: cardiac troponin T (red), fibrillin (green). Myocardium thickens and develops trabeculae; atrium is posterior to the ventricle.
