Results
Specimen not shown: embryonic day 12.5; Msx1tm1Bero/? (more )
Structure Level Pattern Image Note
TS20: brain Present Regionally restricted B-gal activity is seen in the ependymal layer at the dorsal midline of the brain over its entire length.
TS20: subcommissural organ primordium Present

Specimen 2A: embryonic day 14.5; Msx1tm1Bero/Msx1tm1Bero (more )
Structure Level Pattern Image Note
TS22: prosomere 1 Absent 2A In 15 of 15 embryos examined there is lack of B-gal activity in the midline of the pretectum. In a few cases a short remnant of the B-gal domain could be detected just posterior to the pineal anlage.
TS22: subcommissural organ Absent 2A
TS22: midbrain Present Regionally restricted 2A B-gal activity is seen at the dorsal midline.

Specimen not shown: embryonic day 14.5; Msx1tm1Bero/Msx1tm1Bero (more )
Structure Level Pattern Image Note
TS22: prosomere 1 Present Regionally restricted In 15 of 15 embryos examined there is lack of B-gal activity in the midline of the pretectum. In a few cases a short remnant of the B-gal domain could be detected just posterior to the pineal anlage.

Specimen 2B: embryonic day 14.5; Msx1tm1Bero/Msx1+ (more )
