Characteristics and possible function of pinopodes seen on the surface of the receptive human endometrium

A synchronized development of embryo and endometrium is a prerequisite for a successful implantation. During the time of implantation, pinopodes appear on the endometrial surface. The precise function of these structural markers of endometrial receptivity is not known, but it is generally believed that they play a role in the implantation process.Further understanding of the function of these biomarkers and their role in embryo implantation could aid in better diagnosis and treatment of infertile couples in the future.
