Results
Specimen 6A: embryonic day 7.25 (more )
Note: This is a mid primitive streak stage embryo.
Structure Level Pattern Image Note
TS10: extraembryonic mesoderm Present Single cells 6A Expression is localized to a small number (perhaps two) extraembryonic mesoderm cells.
TS10: extraembryonic ectoderm Absent 6A
TS10: extraembryonic visceral endoderm Absent 6A
TS10: primary trophoblast giant cell Absent 6A

Specimen 6B: embryonic day 7.4 (more )
Note: This is a late primitive streak stage embryo.
Structure Level Pattern Image Note
TS10: yolk sac mesoderm Present 6B
TS10: embryo mesoderm Present Regionally restricted 6B Expression is present in the posterior embryonic mesoderm.
TS10: amniotic fold mesoderm Absent 6B There is no expression in extraembryonic mesoderm cells contributing to the formation of the chorion or the amnion.

Specimen 6C: embryonic day 7.5 (more )
Note: This is a neural plate stage embryo.
Structure Level Pattern Image Note
