Objective:To study the expression of matrix metalloproteinase-9 (MMP-9)/tissue inhibitor of metalloproteinase-1(TIMP-1) protein in the implantation window endometrium phase in ovulation normal women and the role of MMP-9/TIMP-1 on embryo implantation.Methods:SEM was used to determine “implantation window” of the mid-secretive phase endometrium in ovulation-normal women.Immunohistochemical analysis was applied to measure the expression of MMP-9/TIMP-1 protein in the implantation window in 15 cases
and MMP-9/TIMP-1 expression in endometrium during different phases were compared.Results:MMP-9/TIMP-1 expression in endometrium was observed in luminal
glandular epithelium and stromal cells in different phases.The expression was lower in proliferative phase
and got to the summit in the implantation window and late secretive phase and it expressed significantly higher in the implantation window phase(P<0.05).There was no difference between the implantation window and late secretive phase.Conclusion:Expression of MMP-9/TIMP-1 in the implantation window phase of endometrium is specific in ovulation normal women and may play an important role in regulating the depth of trophoblast invasion during embryo implantation.
