Structure	Level	Pattern	Image	Note
TS5: inner cell mass	Moderate		2A miR-106a	There is very specific staining in the inner cell mass, although levels appear equal in all cell types.
TS5: embryo	Moderate	Regionally restricted	2A miR-106a	Expression is present in the presumptive primitive endoderm.
TS5: trophectoderm	Moderate		2A miR-106a

Structure	Level	Pattern	Image	Note
TS7: epiblast	Absent		3D
TS7: extraembryonic ectoderm	Very strong		3D
TS7: primitive endoderm	Very strong	Regionally restricted	3D	There is strong expression in the visceral endoderm.

Structure	Level	Pattern	Image	Note
TS9: primitive streak	Absent		4D
TS9: embryo ectoderm	Strong	Regionally restricted	4D	Expression is restricted to cells at least one cell layer removed from the posterior end of the primitive streak.
