node |

detected |
| regional | Cryptic staining is restricted to the ventral mesoderm layer of the node, and is not observed in the overlying dorsal layer that is continuous with the epiblast. |
neural ectoderm |
 |
detected |
| regional | In sections that are immediately rostral to the node, staining is found in the notochordal plate and in a narrow patch of the adjacent midline neuroectoderm. |
notochordal plate |
 |
detected |
| regional | In sections that are immediately rostral to the node, staining is found in the notochordal plate and in a narrow patch of the adjacent midline neuroectoderm. (FigC,F) In frontal sections through more rostral regions of the notochordal plate, this midline neuroectoderm staining becomes slightly broader in extent (Fig D,G) |
embryo mesoderm |
 |
detected |
| regional | Cryptic staining is restricted to the ventral mesoderm layer of the node, and is not observed in the overlying dorsal layer that is continuous with the epiblast. Arrow indicates expression in lateral plate mesoderm |
