The aim of this study was to analyze gene expression profiles from individual endometrial samples obtained from women with repeated implantation failure after IVF in oocyte donation programs. METHODS Seventeen volunteers were recruited: women who had previously participated as recipients in oocyte donation cycles and repeat...

These progenitor cells are thought to be derived from Müllerian duct (MD), the primordial female reproductive tract (FRT). METHODOLOGY/PRINCIPAL FINDINGS We have developed a model...
