Results
Specimen 1A: embryonic day 7.0 (more )
Note: Late midstreak/late streak.
Structure Level Pattern Image Note
TS10: primitive streak Present Regionally restricted 1A Expression began in the most caudal part of the primitive streak, at the junction between extra-embryonic and embryonic tissues.
Specimen 1B: embryonic day 7.0 (more )
Note: Late streak stage.
Structure Level Pattern Image Note
TS10: primitive streak Present Regionally restricted 1B Domain spread along and lateral to the primitive streak.
Specimen 1C: embryonic day 7.0 (more )
Note: Late streak/early bud stage.
Structure Level Pattern Image Note
TS10: primitive streak Present Regionally restricted 1C Domain spread along and lateral to the primitive streak.
Specimen 1D: embryonic day 7.0 (more )
Note: Late streak/early bud/neural plate stage.
Structure Level Pattern Image Note
TS10: primitive streak Present Regionally restricted 1D Transcripts reached that anterior end of the streak; also more widely laterally and anteriorly in the mesodermal wings.
