Results
Specimen 2A: embryonic day 15.5; Efnb2tm1Nwg/Efnb2+ (more )
Note: This is a frontal section from the anterior chiasm.
Structure Level Pattern Image Note
TS23: diencephalon Present 2A Expression is broadly located around the floor of the third ventricle.
TS23: optic chiasma Present 2A Expression is broadly located around the floor of the third ventricle.
Specimen 2B: embryonic day 15.5; Efnb2tm1Nwg/Efnb2+ (more )
Note: This is a frontal section from the midchiasm.
Structure Level Pattern Image Note
TS23: optic chiasma Present 2B Expression is strongest in the region in which retinal axons pause and turn to project ipsilaterally.
Specimen 2C: embryonic day 15.5; Efnb2tm1Nwg/Efnb2+ (more )
Note: This is a frontal section from the posterior chiasm.
Structure Level Pattern Image Note
TS23: diencephalon Present 2C In more caudal sections, staining diminishes.
