Results
Specimen 6A: embryonic day 18.5 (more )
Note: Apex region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6A Expressed in inner and outer hair cells.
Specimen 6B: embryonic day 18.5; Jag1tm1Grid/Jag1tm2Grid, Foxg1tm1(cre)Skm/Foxg1+ (more )
Note: Conditional mutant. Apex region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6B Expressed in inner hair cells. Outer hair cells were not present in the mutant.
Specimen 6C: embryonic day 18.5 (more )
Note: Middle region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6C Expressed in inner and outer hair cells.
Specimen 6D: embryonic day 18.5; Jag1tm1Grid/Jag1tm2Grid, Foxg1tm1(cre)Skm/Foxg1+ (more )
Note: Conditional mutant. Middle region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6D Expressed in both inner and occasionally outer hair cells, although their patterning was clearly abnormal.
Specimen 6E: embryonic day 18.5 (more )
Note: Base region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6E Expressed in inner and outer hair cells.
Specimen 6F: embryonic day 18.5; Jag1tm1Grid/Jag1tm2Grid, Foxg1tm1(cre)Skm/Foxg1+ (more )
Note: Conditional mutant. Base region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: cochlea epithelium Present Regionally restricted 6F No hair cells were present in the base region.
Specimen 6G: embryonic day 18.5 (more )
Note: Utricle region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: utricle epithelium Present Regionally restricted 6G Expressed in the hair cells.
Specimen 6H: embryonic day 18.5; Jag1tm1Grid/Jag1tm2Grid, Foxg1tm1(cre)Skm/Foxg1+ (more )
Note: Conditional mutant. Utricle region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: utricle epithelium Present Regionally restricted 6H The utricular macula is extremely small with very few positive hair cells.
Specimen 6I: embryonic day 18.5 (more )
Note: Saccule region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: saccule epithelium Present Regionally restricted 6I Expressed in the hair cells.
Specimen 6J: embryonic day 18.5; Jag1tm1Grid/Jag1tm2Grid, Foxg1tm1(cre)Skm/Foxg1+ (more )
Note: Conditional mutant. Saccule region. Double labeled: red - Myo7a; green - S100a1 (assay MGI:6763028).
Structure Level Pattern Image Note
TS26: saccule epithelium Present Regionally restricted 6J Expressed in the hair cells. Hair cell differentiation appeared relatively unaffected, although the entire saccular structure was shaped differently than in the controls.
