Althopugh the interaction between trophoblastic L-selectin and endometrial sLeX has been reported as a glycosylation-dependent adhesion mechanism underlying embryo implantation, it was also found that Siglec-6 expressed in the trophectoderm of human embryos play a key role in facilitating embryo attachment via recognizing the sTn-covered receptive endometrium.
