Probe:	s8609b24
Probe preparation:	Antisense labelled with digoxigenin RNA
Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS8: extraembryonic visceral endoderm	Present	Regionally restricted		Expression occurs in the visceral endoderm overlying the extra-embryonic portion of the conceptus and the most proximal region of the epiblast.

TS9: extraembryonic visceral endoderm	Present	Regionally restricted	1A s8609b24_6.5	Visceral endoderm expression covers most of the conceptus, although it is weaker distally and completely absent from the most proximal region.

TS11: extraembryonic visceral endoderm	Present	Regionally restricted	1A s8609b24_7.5	Expression persists in the progeny of the visceral endoderm cells, coming to lie over the extra-embryonic ectoderm; transcripts are still absent from the most proximal visceral endoderm.
