Expression of E-cadherin in Early Mouse Development

Öz

E-cadherin is a member of the cadherin superfamily of calcium-dependent cell adhesion molecules, and has critical roles in cell adhesion during early embryo development. To determine the expression and distribution of E-cadherin, we applied immunofluorescent staining on late 8 cell, morula and blastocyst stage embryos during the experiments. Firstly, we superovulated the females and sacrificed them to isolate oviducts. We flushed 2 cell embryos by using FHM HEPES-buffered medium from the CD1 female mouse oviducts and cultured them in KSOM medium until the blastocyst stage. Embryos were fixed and immunostained with E-cadherin, then images were assessed using a fluorescence microscope. We demonstrate that E-cadherin is expressed throughout the late 8 cell to fully expanded blastocysts. We observed that E-cadherin is present only in the cell-cell contact sites and not in the apical sites of the membrane of late 8 cell stage embryo. In morula, E-cadherin localized on the surface of blastomeres and cell-cell junctions. In blastocyst stage, embryos showed membrane staining in cell-cell contact regions in trophectoderm cells while localized on the surface of inner cell mass. Our results indicate that E-cadherin mediated cell adhesion has major roles on compaction, trophectoderm epithelial differentation and implantation.
