Results
Specimen 1D: embryonic day 14.5 (more )
Note: This is a frontal section from the anterior chiasm.
Structure Level Pattern Image Note
TS22: optic chiasma Present Regionally restricted 1D Expression is not present in this section, although it is present elsewhere in the optic chiasm.
Specimen 1E: embryonic day 14.5 (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS22: optic chiasma Strong Regionally restricted 1E There is discrete expression at the chiasm midline, dorsal to the path of the retinal gangion cells.
Specimen 1F: embryonic day 14.5 (more )
Note: This is a frontal section from the posterior chiasm.
Structure Level Pattern Image Note
TS22: optic chiasma Present Regionally restricted 1F Expression is not present in this section, although it is present elsewhere in the optic chiasm.
Specimen 1J: embryonic day 12.5 (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS20: diencephalon Weak 1J
Specimen 1K: embryonic day 13.5 (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS21: optic chiasma Present 1K Expression is broadly present along the floor of the third ventricle at the chiasm midline.
Specimen 1L: embryonic day 15.5 (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS23: optic chiasma Strong 1L
Specimen 1M: embryonic day 17.0 (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS25: optic chiasma Trace 1M Expression, at best, is only very weakly present.
