Expression of trophinin in human oocytes and preimplantation embryos / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the significance of trophinin expression in human oocytes and preimplantation embryos.</p><p><b>METHODS</b>The expression of trophinin in 9 human oocytes, 16 blastomeres and 12 blastocysts were detected by indirect immunofluorescence assay and observed under laser scanning confocal microscope.</p><p><b>RESULTS</b>Human oocytes, blastomeres and blastocysts were all positive for trophinin expression, and the positivity intensified significantly in the course of the embryonic development (P<0.05).</p><p><b>CONCLUSION</b>Trophinin may play an important role in human embryo implantation by mediating homophilic adhesion between the embryo and the endometrium during the implantation window.</p>
