Probe:	92 kDa type IV collagenase cDNA1
Probe preparation:	Antisense labelled with S35 RNA
Visualized with:	Autoradiography

Structure	Level	Pattern	Image	Note
TS8: trophoblast giant cell	Weak		1C , 1A/B	Expression was seen in some rounded trophoblast cells emerging from the flat layer of trophectoderm at points of contact with the uterine wall.
TS8: embryo	Absent		1A/B , 1C

Structure	Level	Pattern	Image	Note
TS28: uterus	Absent		1A/B	All uterine tissues, including the epithelium, stroma, and the uterine muscle coat were negative.
TS28: decidua	Absent		1A/B
TS28: uterus stroma	Absent		1A/B

Structure	Level	Pattern	Image	Note
TS9: trophoblast giant cell	Present		2C , 2A/B	Intense staining was detected in trophoblast giant cells emerging around the embryo and penetrating the uterine surface epithelium at points of implantation. Also, smaller trophoblast cells in contact with the uterine surface gave signal.
