Figure 4

Immunostaining for caspase-9 and caspase-3 Caspase-9 is expressed in the primary decidual zone around the implantation chamber on day 4.5 pc (a, b). Strong staining for the active caspase-3 is seen in the epithelium of the implantation chamber on day 5.5 pc (c, d) as well as in the adjacent luminal epithelium on day 6.5 pc (e, f). At day 6.5 pc some decidual cells of the primary decidual zone surrounding the embryo are marked by active caspase-3 (g, h). IC, implantation chamber; E, luminal uterine epithelium; am, antimesometrial side; PD, primary decidual zone; Em, embryo. Bar represents 100 μm in a, b and 50 μm in c-h.
