BMP7 coordinates endometrial epithelial cell receptivity for blastocyst implantation through the endoglin pathway in cell lines and a mouse model.

Bone morphogenetic protein (BMP) expression has been observed in the uterus in previous studies. However, the influence of BMP7 on blastocyst implantation remains unclear. Blastocysts first act on luminal endometrial epithelial cells during implantation.
