Immunohistochemistry of Hsp105 in implantation site and inter-implantation segment. The pregnant rats were killed on Day 6, the implantation sites (D6m) and the inter-implantation segments (D6n) were isolated for preparation of immunohistochemistry. Hsp105 expression in endometrium at the implantation site was much stronger than that at the inter-implantation segment. CON, negtive control; le, luminal epithelium; ge, glandular epithelium; s, stroma; de, decidua; em, embryo. Bar = 200 μm.
