Structure Cell Type Level Pattern Image Note
TS15: labyrinthine zone syncytiotrophoblast cell Present Regionally restricted Extended Data 22B -/- Gcm1 , Extended Data 22C -/- Gcm1 Expression is seen in a subset of SynTII cells and precursors; in the mutant chorioallantoic branching and SynTII development is comparable to that seen in controls.

Specimen Tgds +/- E9.5: embryonic day 9.5; Tgdsem1(IMPC)Mbp/Tgds+ (more )

Structure Cell Type Level Pattern Image Note
TS15: labyrinthine zone syncytiotrophoblast cell Present Regionally restricted Extended Data 23C -/- Gcm1 , Extended Data 23B -/- Gcm1 Expression is seen in a subset of SynTII cells and precursors; in the mutant chorioallantoic branching and SynTII development is comparable to that seen in controls.

Specimen Tgds +/- E10.5: embryonic day 10.5; Tgdsem1(IMPC)Mbp/Tgds+ (more )

TS17: labyrinthine zone syncytiotrophoblast cell Present Regionally restricted Extended Data 23E +/- Gcm1 , Extended Data 23F +/- Gcm1 Expression is seen in a subset of SynTII cells and precursors.

Specimen Tgds -/- E10.5: embryonic day 10.5; Tgdsem1(IMPC)Mbp/Tgdsem1(IMPC)Mbp (more )
Structure Cell Type Level Pattern Image Note
TS17: labyrinthine zone syncytiotrophoblast cell Present Regionally restricted Extended Data 23F -/- Gcm1 , Extended Data 23E -/- Gcm1 Expression is seen in a subset of SynTII cells and precursors; in mutants expression is sparse as chorioallantoic branching and SynTII layer formation is nearly absent.
