Journal of Experimental & Clinical Assisted Reproduction Molecular Mechanisms in Uterine Epithelium during Trophoblast Binding: the Role of Small Gtpase Rhoa in Human Uterine Ishikawa Cells

Background: The purpose of this study was to localize the expression of steroid sulfatase (STS) in cumulus cells and to determine the relationship between STS mRNA expression and the serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol and progesterone.
