Implantation And Diagnostics Of Endometrial Receptivity

Objective: Literature review of endometrial receptivity in embryo implantation and its diagnostic possibilities.Design: Literature review.Setting: Department of Obstetrics and Gynecology, University Hospital, Faculty of Medicine, Palacky University, Olomouc; Institute of Molecular and Translational Medicine, Faculty of Medicine and Dentistry, Palacky University, Olomouc.Results: Endometrial tissue is very dynamic, undergoing cyclic proliferation, differentiation and cell transportation, especially of immune system cells under the influence of circulating estradiol and progesterone. Endometrial remodelling during embryo implantation is controlled by decidual cells senescence and effectivity of their immunologic destruction.Endometrial receptivity can be assessed by transcriptomic profiling of endometrial biopsy using ERA system or proteomic analysis of either endometrial secretome or cervical mucus by gel electrophoresis (DIGE) or mass spectrometry (MS).Conclusion: With respect to recent discoveries in endometrial physiology and molecular biology, clinical application of proteomic approaches in research of potential biomarkers of endometrial receptivity could be of interest.
