Results
Specimen 1F: embryonic day 15.5 (more )
Structure Level Pattern Image Note
TS23: skeletal muscle Present Regionally restricted 1F Expression was detected in perineal muscles, which comprises external anal sphincter, external urethrovaginal sphincter, levator ani, bulbospongiosus and ischiocavernosus muscles.

Specimen 5A: embryonic day 11.5 (more )
Structure Level Pattern Image Note
TS19: skeletal musculature Present Regionally restricted 5A Expression was detected in the ventral muscle mass of hindlimb.

Specimen 5B: embryonic day 12.5 (more )
Structure Level Pattern Image Note
TS20: skeletal muscle Present Regionally restricted 5B Expression was detected in the ventrocaudal hindlimb muscle mass, which began to extend towards the genital tubercle.

Specimen 5C: embryonic day 13.0 (more )
Structure Level Pattern Image Note
TS21: skeletal muscle Present Regionally restricted 5C Expression was detected in the extension of the hindlimb muscle mass that had reached the base of the tubercle.

Specimen 5D: embryonic day 13.5 (more )
Structure Level Pattern Image Note
TS21: skeletal muscle Present Regionally restricted 5D Expression was detected in the muscle mass at the base of the genital tubercle that had begun to split into future single muscles.

Specimen 5E: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: skeletal muscle Present Regionally restricted 5E Expression was detected in the perineal anlage forming separate muscle branches around the openings of the already septated cloaca.

Specimen 5J: embryonic day 15.5; Meox2tm1Vpa/Meox2tm1Vpa (more )
Structure Level Pattern Image Note
TS23: skeletal muscle Present Regionally restricted 5J Expression was detected in the full complement of perineal muscles as in wild type.
