Results
Specimen 1a: embryonic day 13.0; Etn2Sd/Etn2+ (more )
Note: Caudal-most section in the spinal cord, 2mm from the tip of the tail.
Structure Level Pattern Image Note
TS21: embryo Present 1a Expression was detected in many tissues outside of the central nervous system.
TS21: spinal cord ventricular layer Present Regionally restricted 1a Expression was detected in bilateral foci in the ventral ventricular zone in regions of the spinal cord that were associated with a floor plate.

Specimen 1b: embryonic day 13.0; Etn2Sd/Etn2+ (more )
Note: More anterior than 1a.
Structure Level Pattern Image Note
TS21: embryo Present 1b Expression was detected in many tissues outside of the central nervous system.
TS21: spinal cord ventricular layer Absent 1b Where there was no floor plate, there was no expression in that region of the spinal cord.

Specimen 1c: embryonic day 13.0; Etn2Sd/Etn2+ (more )
Note: More anterior than 1b.
Structure Level Pattern Image Note
TS21: embryo Present 1c Expression was detected in many tissues outside of the central nervous system.
TS21: spinal cord ventricular layer Present Regionally restricted 1c Expression was detected in bilateral foci in the ventral ventricular zone in regions of the spinal cord that were associated with a floor plate.

Specimen 2A: embryonic day 13.0; Etn2Sd/Etn2+ (more )
Note: Section from the caudal region with a floor plate.
Structure Level Pattern Image Note
TS21: spinal cord ventricular layer Present 2A

Specimen 2B: embryonic day 13.0; Etn2Sd/Etn2+ (more )
Note: Section from the caudal region without a floor plate.
Structure Level Pattern Image Note
TS21: spinal cord ventricular layer Absent 2B

Specimen 3a: embryonic day 15.0; Etn2Sd/Etn2+ (more )
Note: Section from the caudal region, lacking a floor plate.
Structure Level Pattern Image Note
TS23: spinal cord Absent 3a There were regions of the spinal cord that lacked a floor plate that also lacked expression.

Specimen 3b: embryonic day 15.0; Etn2Sd/Etn2+ (more )
Note: Section from the caudal region, lacking a floor plate.
Structure Level Pattern Image Note
TS23: spinal cord Present 3b There were regions of the spinal cord that lacked a floor plate, but expression was detected in dispersed cells.
TS23: spinal cord ventricular layer Absent 3b If there were expressing cells dispersed in the spinal cord section, they were not found at the ventricular surface.

Specimen 3c: embryonic day 15.0; Etn2Sd/Etn2+ (more )
Note: More anterior section than 3b, possesses a floor plate.
Structure Level Pattern Image Note
TS23: spinal cord Present 3c
