Structure	Level	Pattern	Image	Note
TS13: ectoplacental cone	Present		4D
TS13: trophoblast giant cell	Present		4D

Structure	Level	Pattern	Image	Note
TS13: ectoplacental cone	Present		4E	These cells are vastly underrepresented in the mutants. (BrdU labeling demonstrates they display DNA replication defects.)
TS13: trophoblast giant cell	Present		4E	These cells are vastly underrepresented in the mutants. (BrdU labeling demonstrates they display DNA replication defects.)

Structure	Level	Pattern	Image	Note
TS11: ectoplacental cone	Present		5E	This includes expression in the secondary trophoblast giant cells.

Structure	Level	Pattern	Image	Note
TS11: ectoplacental cone	Present		5F	This structure is abnormally small in presumptive mutants. This includes a reduction in the number of secondary trophoblast giant cells.

Structure	Level	Pattern	Image	Note
TS11: ectoplacental cone	Present		5G	This structure is abnormally small in presumptive mutants. This includes a reduction in the number of secondary trophoblast giant cells.

Structure	Level	Pattern	Image	Note
TS11: ectoplacental cone	Present		5H	This structure is abnormally small in presumptive mutants. This includes a reduction in the number of secondary trophoblast giant cells.
