Results
Specimen 3I: embryonic day 6.5 (more )
Note: Double labeled: red - Otx2; green - Lhx1 (assay MGI:5688189).
Structure Level Pattern Image Note
TS8: anterior visceral endoderm Present 3I
TS8: epiblast Present 3I
Specimen 3I': embryonic day 6.5; Otx2tm9Asim/Otx2tm11Asim (more )
Note: Double labeled: red - Otx2; green - Lhx1 (assay MGI:5688189).
Structure Level Pattern Image Note
TS8: epiblast Weak 3I'
TS8: anterior visceral endoderm Weak Regionally restricted 3I' Some cells showed a reduction of expression in the mutant. However, the visceral endoderm marker Lhx1 was expressed normally.
Specimen 6F: embryonic day 6.5 (more )
Note: Double labeled: red - Otx2; green - Lhx1 (assay MGI:5688189).
Structure Level Pattern Image Note
TS8: primitive endoderm Present 6F
Specimen 6J: embryonic day 6.5; Otx2tm10Asim/Otx2tm11Asim (more )
Note: Double labeled: red - Otx2; green - Lhx1 (assay MGI:5688189).
Structure Level Pattern Image Note
TS8: primitive endoderm Present Single cells 6J Only a few visceral endoderm cells retained immunostaining in the mutant compared to wild type.
Specimen 9C: embryonic day 6.5; Otx2tm1Pas/Otx2+ (more )
Note: Double labeled: red - Otx2 protein; green - Otx2 reporter (assay MGI:5688750).
Structure Level Pattern Image Note
TS8: primitive endoderm Present 9C Most, but not all, immunopositive visceral endoderm cells were also beta-galactosidase-positive.
Specimen 9F: embryonic day 6.5; Otx2tm1Pas/Otx2tm9Asim (more )
Note: Double labeled: red - Otx2 protein; green - Otx2 reporter (assay MGI:5688750).
Structure Level Pattern Image Note
TS8: primitive endoderm Present 9F The majority of immunopositive cells were beta-galactosidase-positive.
Specimen 9I: embryonic day 6.5; Otx2tm1Pas/Otx2tm10Asim (more )
Note: Double labeled: red - Otx2 protein; green - Otx2 reporter (assay MGI:5688750).
Structure Level Pattern Image Note
TS8: primitive endoderm Present Single cells 9I A few cells were immunopositive, some were beta-galactosidase-positive and some were negative.
Specimen 9L: embryonic day 6.5; Otx2tm1Pas/Otx2tm10Asim (more )
Note: Double labeled: red - Otx2 protein; green - Otx2 reporter (assay MGI:5688750).
Structure Level Pattern Image Note
TS8: primitive endoderm Present Single cells 9L A few cells were immunopositive, some were beta-galactosidase-positive and some were negative.
