Results
Specimen 1a: embryonic day 1.0 (more )
Note: early two-cell
Structure Level Pattern Image Note
TS2: 2-cell stage embryo Present Patchy 1a Fine speckled staining in the cortical region of the nucleolus precursor bodies. No staining was observed in the compact nucleolus precursor bodies inner mass or core.

Specimen 1c: embryonic day 1.0 (more )
Note: late two-cell
Structure Level Pattern Image Note
TS2: 2-cell stage embryo Present Regionally restricted 1c Expressed as a discontinuous fluorescent cortical layer of the nucleolus precursor bodies. No staining was observed in the compact nucleolus precursor bodies core.

Specimen 1e: embryonic day 2.0 (more )
Note: four-cell
Structure Level Pattern Image Note
TS3: 4-cell stage embryo Strong Regionally restricted 1e Expressed as a continuous fluorescent cortical layer of the nucleolus precursor bodies. No staining was observed in the compact nucleolus precursor bodies core.

Specimen 1g: embryonic day 2.5 (more )
