Figure 3. Heart Lumen Cross sections, Adult Heart Staining and Cardiac Marker genes.
A. Schematic overview and fluorescent image of the embryonic heart tube (early stage 17), with domains highlighted. Cardiac nuclei are labeled with anti-Neuromancer1 (blue), basal + luminal domains are labeled with anti-Dystroglycan (red), and the luminal domain is marked with anti-Slit (green; for more markers see Table 2). Adult heart tube stained against F-actin. B. Combinatorial code of transcription factors and signaling pathways to identify embryonic cardioblast and pericardial cell types. See Table 2 for references.
