P-552: Differential gene expression in isolated endometrial glandular and stromal cells throughout the window of implantation

Abstract

We have previously established endometrial gene expression profiles during the early and mid-secretory phases of the natural cycle using a genomic microarray approach. We identified four genes with high potential functional significance based upon the demonstration of putative estrogen receptor elements and up-regulation between 3-35- fold comparing the pre-receptive and the receptive endometrium. Here, we aimed to localize and further characterize the temporal expression of these genes.
