Original studies on endometrial transcriptomics in assisted reproductive medicine Most of these studies investigate the transcriptomic signature in the whole endometrial tissue without separating the different compartments. However, in some studies, laser capture micro-dissection has facilitated specific compartment gene expression profiles Yanaihara et al.
Even the specific profiles for stromal cells and glands at different depths in the endometrium have been reported Gaide Chevronnay et al. Several groups have used transcriptomics to search for the molecular diagnosis of the different phases of the human endometrium Carson et al.

Abstract Human implantation is a complex process requiring synchrony between a healthy embryo and a functionally competent or receptive endometrium. Diagnosis of endometrial receptivity ER has posed a challenge and so far most available tests have been subjective and lack accuracy and a predictive value. Microarray technology has allowed identification of the transcriptomic signature of the window of receptivity window of implantation WOI.

In , children were admitted to the Noyes Home, with 50 percent admitted for emergency shelter reasons. There are four types of admissions at the Noyes Home: Children who have become homeless are placed in the safe keeping of the Noyes Home by family members who have lost their home. Families who experience emergencies and do not have a place where their children can stay can also utilize the services of the Noyes Home.

Their use is also known for immobilizing nucleic acids which are complementary to a variety of genes, being applied to the field of chemistry, biology, medicine and medical diagnostics US 6, , B1. Microarrays are currently being used to make comparisons based on genomic data and to research different systems. There are different patent and non-patent literature publications on this subject.
Microarray technology has allowed globally studying the gene expression of the endometrium under physiological conditions during the different phases of the menstrual cycle in the natural cycle Ponnampalam et al. With respect to the human window of implantation, gene expression profiles of the endometrium in the natural cycle have been described Borthwick et al.
The gene expression profile of the endometrium during the window of implantation in stimulated cycles has also been analyzed Mirkin et al.

References Abstract Over the last decade, research to improve success rates in reproductive medicine has focused predominantly on the understanding and optimization of embryo quality. However, the emergence of personalized medicine in ovulation induction and embryology has shifted the focus to assessing the individual status of the endometrium. The endometrium is considered receptive during an individually defined period, the window of implantation WOI , when the mother permits a blastocyst to attach and implant.
This individual receptivity status can now be objectively diagnosed using the endometrial receptivity array ERA developed in The ERA, together with a computational algorithm, detects the unique transcriptomic signature of endometrial receptivity by analyzing differentially expressed genes and reliably predicting the WOI.
We investigated histological dating, αvβ3 integrin expression, and pinopod formation in 45 endometrial biopsy specimens obtained in 15 primary infertility patients (mean duration of infertility, yr; range, 2–8 yr) undergoing a routine work-up.
MMPs are produced as inactive precursors that require activation by other peptidases, denaturants, or heat. Cell adhesion receptors known as integrins appear to have a role in MMP expression and function. Plasminogen, its activators, and its inhibitors appear to participate in this process. Human endometrium, embryos, and trophoblasts express both uPA and its receptor, and mutations in these have been associated with implantation failure. Polycystic ovary syndrome PCOS is associated with elevated PAI-1 activity, which may contribute to the higher than expected rate of pregnancy loss via this pathway.
Activation of matrix metalloproteinases MMP. This process is inhibited by tissue inhibitors of metalloproteinases TIMPs. Integrin cell adhesion molecules Integrins, one member of a larger family of cell adhesion molecules, have been well studied at the levels of the embryo, trophoblast, and endometrial epithelium and stroma throughout the menstrual cycle and into pregnancy Fig. They observed that in uteri obtained prior to cycle day 20, all embryos were free-floating in the tubes or uterus, while in uteri obtained after day 21 the embryos were attached to the uterine lining.
Many subsequent studies have helped establish that peak uterine receptivity is between cycle days 20 and 24 of a normalized day cycle. This could prove to be useful for future diagnostic and therapeutic considerations for the infertile couple. Inmmunohistochemical staining was assessed by a blinded observer using the semiquantitative HSCORE ranging from 0 to 4 and correlated to the estimate of histologic dating based on pathologic criteria or by last menstrual period LMP in patients undergoing therapeutic pregnancy termination.
Luteal Progesterone Relates to Histological Endometrial Maturation in Fertile Women
Inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures, whereas the embryo itself is responsible for only one-third of these failures Slide 6 Human embryo implantation is a three-stage process apposition, adhesion and invasion Implantation involves embryo apposition and adhesion to the endometrial epithelium penetration through the epithelium and invasion of the embryonic trophoblast through the endometrial stroma.
On the blastocyst, on the other hand, it occurs at a location where there has been enough lysis of the zona pellucida to have created a rupture to enable direct contact between the underlying trophoblast and the decidua of the endometrium. Slide 9 Endometrial morphological features classical work describing the dating of the endometrium is done by Noyes et al.
Moreover, as described in Labarta et al., histological dating (Noyes’ criteria,) revealed the absence of endometrial maturation advancement during the implantation window (hCG+7) in patients under COS protocols, regardless of the used GnRH analogues and the serum [P] on the day of hCG administration.
To examine the relationship between endometrial histological maturation and reproductive hormones, we studied 11 fertile women, aged 18—37 yr. All participants had had at least 1 previous pregnancy and cycled regularly, every 25—35 days. Women collected daily, first morning voided urine for measurement of estradiol and progesterone metabolite excretion, estrone conjugates E1c , and pregnanediol glucuronide Pdg , respectively, throughout the cycle of study.
Hormones were normalized for creatinine. Between 7—9 days after home detection of a LH surge Sure Step , participants underwent an endometrial biopsy using a small bore Pipelle catheter. Tissue was prepared for histological and biochemical analyses. The histological analysis is reported herein. Endometrium was dated by 3 authors N. Final dating was agreed upon based upon the method of Noyes et al. E1c and Pdg were integrated throughout the cycle using the trapezoidal rule, and correlations were sought between deviation from expected histology based upon urinary hormones and LH surge and integrated hormone values.
No relationship could be found between histological lagging of endometrial maturation and lower excretion of E1c. We conclude that normal fertile women experience a wide range of hormone concentrations in the face of normal endometrial maturation. Progesterone appears to exert a dose-related effect on endometrial maturation, and the techniques we used, although relatively crude clinical measures, appeared to be sufficient to detect this relationship.
Estradiol stimulation results in proliferation of the basalis and functionalis, whereas progesterone promotes glandular development and secretion and is believed to initiate the changes necessary for implantation.
