The cells of the epiblast of a developing mammalian embryo display E-cadherins on their surfaces, which promote their close association with one another. E-cadherins are a type of cell adhesion molecule that mediates calcium-dependent cell-cell adhesion. They are important in the formation of tight junctions between cells and the establishment of epithelial cell polarity.
