Results
Specimen 4A: embryonic day 2.5 (more )
Note: 8-cell embryo.
Structure Level Pattern Image Note
TS3: 8-cell stage embryo Present 4A In the majority of embryos at this stage expression is unlocalized within the cells.
Specimen 4B: embryonic day 2.5 (more )
Note: 8-cell embryo.
Structure Level Pattern Image Note
TS3: 8-cell stage embryo Present Non-Uniform 4B In a minority of embryos at this stage expression is apically localized.
Specimen 4C: embryonic day 3.0 (more )
Note: 20-cell embryo.
Structure Level Pattern Image Note
TS4: compacted morula Present Non-Uniform 4C Expression is present in all cells; it is detected at the entire cell membrane.
Specimen 4D: embryonic day 3.5 (more )
Note: 33-cell embryo.
Structure Level Pattern Image Note
TS4: blastocyst Present Non-Uniform 4D Expression levels are reduced in inside cells.
Specimen 4F: embryonic day 3.0 (more )

Specimen 5A: embryonic day 3.5 (more )
Note: This is a blastocyst stage embryo. Double labeled: red - Krt8; white - Cdx2 (assay MGI:3777138).
Structure Level Pattern Image Note
TS4: trophectoderm Present Non-Uniform 5A Krt8 Expression is enriched in the cell membrane.

Specimen 5D: embryonic day 3.0; Cdx2tm1Fbe/Cdx2tm1Fbe (more )
Note: 16-cell embryo. Double labeled: red - Krt8; white - Cdx2 (assay MGI:3777138).
Structure Level Pattern Image Note
TS4: compacted morula Present Non-Uniform 5D Krt8 Expression levels are reduced compared to those seen in wild type, but it is still apically localized.
