Molecular Implantation Cartoon

Compartment colours
This is a hybrid cartoon, based on mouse and human studies, portraying compartment- and cell-type–specific expression of molecules and their potential functions necessary for uterine receptivity, implantation and decidualization. Interplay of ovarian P4- and/or E2-dependent and P4- and/or E2-independent factors in the pregnant uterus in specific compartments contributes to the success of implantation in a juxtacrine/paracrine/autocrine manner. During attachment, interactions between the blastocyst and luminal epithelium (LE) involve ErbB1/4 (blue) and both transmembrane (TM) and soluble (Sol) forms of HB-EGF, as well as L-selectin ligands (sLE) expressed by the luminal epithelium to L-selectin receptors on the blastocyst. The other key signaling pathways for uterine receptivity and implantation are also shown.
  • blue - stroma
  • pink - luminal epithelium
  • orange - glandular epithelium
  • purple - epithelium at the attachment site.
