Abstract
The implantation rate of in vitro fertilization (IVF)-derived blastocysts after embryo transfer remains low, suggesting that the inadequate expression of specific proteins in culture-induced IVF-derived blastocysts contributes to low implantation rates. Therefore, treatment with appropriate regulation may improve the blastocyst implantation ability. This study demonstrated that the combination of l-arginine (Arg) and l-leucine (Leu) exerts distinct effects on IVF-derived mouse blastocysts. Arg with Leu promotes blastocyst implantation, whereas Arg alone decreases the blastocyst ability. Integrin α5β1 expression was increased in blastocysts treated with Arg and Leu. Arg with Leu also increased reactive oxygen species (ROS) levels and showed a positive correlation with integrin α5β1. Ascorbic acid, an antioxidant, decreased ROS and integrin α5β1 levels, which were elevated by Arg with Leu. Meanwhile, the mitochondrial membrane potential (ΔΨm) in blastocysts did not differ between treatments. Glutathione peroxidase (GPx) is involved in ROS scavenging using glutathione (GSH) as a reductant. Arg with Leu decreased GPx4 and GSH levels in blastocysts, and blastocysts with higher ROS levels had lower GPx4 and GSH levels. In contrast, Arg alone increased the percentage of caspase-positive cells, indicating that Arg alone, which attenuated implantation ability, was associated with apoptosis. This study revealed that elevated ROS levels induced by Arg with Leu stimulated integrin α5β1 expression, thereby enhancing implantation capacity. Our results also suggest that ROS were not due to increased production by oxidative phosphorylation, but rather to a reduction in ROS degradation due to diminished GPx4 and GSH levels.

Abstract
PURPOSE Estrogen is well-known for preparing uterine receptivity. However, its roles in regulating embryo development and implantation are unclear. Our objective was to characterize estrogen receptor 1 (ESR1) in human and mouse embryos and determine the effect of estradiol (E2) supplementation on pre- and peri-implantation blastocyst development. METHODS Mouse embryos, 8-cell through hatched blastocyst stages, and human embryonic days 5-7 blastocysts were stained for ESR1 and imaged using confocal microscopy. We then treated 8-cell mouse embryos with 8 nM E2 during in vitro culture (IVC) and examined embryo morphokinetics, blastocyst development, and cell allocation into the inner cell mass (ICM) and trophectoderm (TE). Finally, we disrupted ESR1, using ICI 182,780, and evaluated peri-implantation development. RESULTS ESR1 exhibits nuclear localization in early blastocysts followed by aggregation, predominantly in the TE of hatching and hatched blastocysts, in human and mouse embryos. During IVC, most E2 was absorbed by the mineral oil, and no effect on embryo development was found. When IVC was performed without an oil overlay, embryos treated with E2 exhibited increased blastocyst development and ICM:TE ratio. Additionally, embryos treated with ICI 182,780 had significantly decreased trophoblast outgrowth during extended embryo culture. CONCLUSION Similar ESR1 localization in mouse and human blastocysts suggests a conserved role in blastocyst development. These mechanisms may be underappreciated due to the use of mineral oil during conventional IVC. This work provides important context for how estrogenic toxicants may impact reproductive health and offers an avenue to further optimize human-assisted reproductive technology (ART) to treat infertility.

Abstract
Most pregnancy losses worldwide are caused by implantation failure for which there is a lack of effective therapeutics. Extracellular vesicles are considered potential endogenous nanomedicines because of their unique biological functions. However, the limited supply of ULF-EVs prevents their development and application in infertility diseases such as implantation failure. In this study, pigs were used as a human biomedical model, and ULF-EVs were isolated from the uterine luminal. We comprehensively characterized the proteins enriched in ULF-EVs and revealed their biological functions in promoting embryo implantation. By exogenously supplying ULF-EVs, we demonstrated that ULF-EVs improve embryo implantation, suggesting that ULF-EVs are a potential nanomaterial to treat implantation failure. Furthermore, we identified that MEP1B is important in improving embryo implantation by promoting trophoblast cell proliferation and migration. These results indicated that ULF-EVs can be a potential nanomaterial to improve embryo implantation.

Abstract
Purpose This study aimed to examine expressions of iNOS and phosphorylated eNOS (p-eNOS) in implantation-induced blastocysts. We also examined the upstream of p-eNOS. Methods To address the protein expressions in implantation-induced blastocysts, we performed immunohistochemical analysis using a delayed implantation mouse model. Immunostaining for iNOS, p-eNOS, and p-Akt was done. To address the relationship between p-eNOS and p-Akt, activated blastocysts were treated with an Akt inhibitor, MK-2206. Results iNOS expression was at low levels in dormant blastocysts, whereas the expression was significantly increased in the activated blastocysts. Double staining of p-eNOS and p-Akt in individual blastocysts showed colocalization of p-eNOS and p-Akt of the trophectoderm. p-eNOS and p-Akt expressions were at low levels in dormant blastocysts, whereas both of them were significantly increased in the activated blastocysts. Both dormant and activated blastocysts showed significant positive correlations between p-eNOS and p-Akt. MK-2206 treatment for activated blastocysts showed that blastocysts with lower p-Akt had significantly lower p-eNOS levels. Conclusions iNOS and p-eNOS, Ca2+ independent NOS, are upregulated by E2 in the blastocysts during implantation activation. Furthermore, p-eNOS is upregulated in implantation-induced blastocysts downstream of p-Akt.

Abstract
The morula-to-blastocyst transition (MBT) culminates with formation of inner cell mass (ICM) and trophectoderm (TE) lineages. Recent studies identified signaling pathways driving lineage specification, but some features of these pathways display significant species divergence. To better understand evolutionary conservation of the MBT, we completed a meta-analysis of RNA sequencing data from five model species and ICMTE differences from four species. Although many genes change in expression during the MBT within any given species, the number of shared differentially expressed genes (DEGs) is comparatively small, and the number of shared ICMTE DEGs is even smaller. DEGs related to known lineage determining pathways (e.g., POU5F1) are seen, but the most prominent pathways and functions associated with shared DEGs or shared across individual species DEG lists impact basic physiological and metabolic activities, such as TCA cycle, unfolded protein response, oxidative phosphorylation, sirtuin signaling, mitotic roles of polo-like kinases, NRF2-mediated oxidative stress, estrogen receptor signaling, apoptosis, necrosis, lipid and fatty acid metabolism, cholesterol biosynthesis, endocytosis, AMPK signaling, homeostasis, transcription, and cell death. We also observed prominent differences in transcriptome regulation between ungulates and nonungulates, particularly for ICM- and TE-enhanced mRNAs. These results extend our understanding of shared mechanisms of the MBT and formation of the ICM and TE and should better inform the selection of model species for particular applications.

Abstract
Background Previous studies have demonstrated that high levels of estradiol (E2) impair blastocyst implantation through effects on the endometrium; however, whether high E2 directly affects blastocysts is not well established. The present study sought to clarify the direct impacts of high E2 levels on blastocysts in vitro. Methods ICR virgin albino mice were used. Using an in-vitro 8-day blastocyst culture model, immunofluorescence staining for the estrogen receptor (ER), blastocyst outgrowth assays, differential staining and TUNEL assays of blastocysts, and embryo transfer, we investigated the main outcomes of exposure to different E2 concentrations (10−7 to 10−4 M) in vitro and in vivo. Results ERα and ERβ expression were detected in pre-implantation stage embryos. In vitro exposure of blastocysts to 10−4 M E2 for 24 h followed by 7 days culture in the absence of E2 caused severe inhibition of implantation and post-implantation development. The late adverse effects of E2 on post-implantation development still occurred at concentrations of 10−7 to 10−5 M. In addition, blastocyst proliferation was reduced and apoptotic cells were increased following exposure to 10−4 M E2. Using an in vivo embryo-transfer model, we also showed that treatment with high E2 resulted in fewer implantation sites (38% vs. 72% in control) and greater resorption of implanted blastocysts (81% vs. 38% in control). Conclusion Exposure to high E2 concentrations in vitro is deleterious to blastocyst implantation and early post-implantation development, mainly owing to direct impacts of E2 on implanting blastocysts. In clinical assisted reproductive technique (ART), high serum E2 concentrations not only affects the endometrium, but also affects blastocysts directly at the period of implantation.

Improvement of implantation potential in mouse blastocysts derived from IVF by combined treatment with prolactin, epidermal growth factor and 4-hydroxyestradiol. Mol Hum Reprod 2018; 23:557-570.

Abstract
STUDY QUESTION Can supplementation of medium with prolactin (PRL), epidermal growth factor (EGF) and 4-hydroxyestradiol (4-OH-E2) prior to embryo transfer improve implantation potential in mouse blastocysts derived from IVF? SUMMARY ANSWER Combined treatment with PRL, EGF and 4-OH-E2 improves mouse blastocyst implantation rates, while alone, each factor is ineffective. WHAT IS KNOWN ALREADY Blastocyst dormancy during delayed implantation caused by ovariectomy is maintained by continued progesterone treatment in mice, and estrogen injection rapidly activates blastocysts to implantation-induced status in vivo. While the expression of many proteins is upregulated in implantation-induced blastocysts, selective proteolysis by proteasomes, such as estrogen receptor α (ESR1), occurs in implantation-induced blastocysts to achieve implantation-competent status. It is worth evaluating the proteins expressed during these periods to identify humoral factors that might improve the implantation potential of IVF-derived blastocysts because the poor quality of embryos obtained by IVF is one of the major causes of implantation failure. STUDY DESIGN, SIZE, DURATION Superovulated oocytes from ICR mice were fertilized with spermatozoa and then cultured in vitro in potassium simplex optimized medium (KSOM) without phenol red (KSOM-P) for 90-96 h. Blastocysts were treated with PRL (10 or 20 mIU/mL), EGF (5 or 10 ng/mL) or 4-OH-E2 (1 or 10 nM) in KSOM-P for 24 h. PARTICIPANTS/MATERIALS, SETTING, METHODS Levels of breast cancer 1 (BRCA1), EGF receptor (EGFR, also known as ERBB1), ERBB4, tubulointerstitial nephritis antigen-like 1 (TINAGL1) and ESR1 protein were examined with immunohistochemical analysis using immunofluorescence methods and confocal laser scanning microscopy. For embryo transfer, six blastocysts were suspended in HEPES-buffered KSOM-P medium and transferred into the uteri of recipient mice on the morning of Day 4 (0900-1000 h) of pseudopregnancy (Day 1 = vaginal plug). The number of implantation sites was then recorded on Day 6 using the blue dye method. MAIN RESULTS AND THE ROLE OF CHANCE PRL, EGF and 4-OH-E2 each promoted BRCA1 protein level in the trophectoderm (TE). While PRL treatment resulted in an increase in EGFR, EGF increased both EGFR and ERBB4 in the blastocyst TE. TINAGL1 in the TE was enhanced by 4-OH-E2, which also increased localization of this protein to the basement membrane. Treatment with PRL, EGF or 4-OH-E2 alone did not improve blastocyst implantation rates. Combined treatment with PRL, EGF and 4-OH-E2 resulted in increased levels of EGFR, ERBB4, TINAGL1 and BRCA1 in the TE, whereas ESR1 was not upregulated in the treated blastocysts. Furthermore, combined treatment with PRL, EGF and 4-OH-E2 improved blastocyst implantation rates versus control (P = 0.009). LARGE SCALE DATA Not applicable. LIMITATIONS, REASONS FOR CAUTION Our studies were carried out in a mouse model, and the conclusions were drawn from limited results obtained from one species. Whether the increase in EGFR, ERBB4 and TINAGL1 protein in the TE improves implantation potential of blastocysts needs to be further studied experimentally by assessing other expressed proteins. The influence of combined supplementation in vitro of PRL, EGF and 4-OH-E2 on implantation also requires further examination and optimization in human blastocysts before it can be considered for clinical use in ART. WIDER IMPLICATIONS OF THE FINDINGS Enhanced implantation potential by combined treatment with PRL, EGF and 4-OH-E2 appears to result in the upregulation of at least two distinct mechanisms, namely signaling via EGF receptors and basement membrane formation during the peri-implantation period in mice. While PRL, EGF and 4-OH-E2 each promoted BRCA1 protein level in the TE, treatment with each alone did not improve blastocyst implantation. Therefore, BRCA1 protein appears to be unnecessary for the attachment reaction in blastocysts in mice Combined supplementation of PRL, EGF and 4-OH-E2 might also be of relevance for embryo transfer of human IVF-derived blastocysts for ART.

Abstract
The success of implantation is an interactive process between the blastocyst and the uterus. Synchronized development of embryos with uterine differentiation to a receptive state is necessary to complete pregnancy. The period of uterine receptivity for implantation is limited and referred to as the “implantation window”, which is regulated by ovarian steroid hormones. Implantation process is complicated due to the many signaling molecules in the hierarchical mechanisms with the embryo-uterine dialogue. The mouse is widely used in animal research, and is uniquely suited for reproductive studies, i.e., having a large litter size and brief estrous cycles. This review first describes why the mouse is the preferred model for implantation studies, focusing on uterine morphology and physiological traits, and then highlights the knowledge on uterine receptivity and the hormonal regulation of blastocyst implantation in mice. Our recent study revealed that selective proteolysis in the activated blastocyst is associated with the completion of blastocyst implantation after embryo transfer. Furthermore, in the context of blastocyst implantation in the mouse, this review discusses the window of uterine receptivity, hormonal regulation, uterine vascular permeability and angiogenesis, the delayed-implantation mouse model, morphogens, adhesion molecules, crosslinker proteins, extracellular matrix, and matricellular proteins. A better understanding of uterine and blastocyst biology during the peri-implantation period should facilitate further development of reproductive technology.

[PMID: 27939940 DOI: 10.1016/j.lfs.2016.12.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 11/23/2016] [Accepted: 12/03/2016] [Indexed: 12/19/2022]
Abstract
AIMS The role of estrogen in embryo implantation in golden hamster (Mesocricetus auratus) is still ambiguous. In order to clarify it, we investigated the spatial distribution and expression of estrogen receptors, ER-α and ER-β in the uterus of pregnant hamster during peri-implantation period and identified the effect of estrogen receptor antagonist ICI-182,780 on the embryo implantation. MAIN METHODS We performed in vivo experiments on early pregnant hamsters involving treatment with ICI-182,780, an estrogen receptor antagonist. Immunohistochemistry, western blot analysis and quantitative PCR were employed to evaluate the spatio-temporal distribution and expression of ER-α and ER-β in the uterus of normal early pregnant and treated hamsters. KEY FINDINGS Results showed that embryo implantation was completely absent in ICI-182,780 treated uterine horn while, normal implantation occurred in control and vehicle treated horns. Both the receptors were differentially expressed in the uterus of hamster from day 1 (D1) to day7 (D7). In contrast, treated horns without any implantation site showed no trace of any receptors. Protein and mRNA expression of both the receptors were high around the day of implantation while, ER-β expression was up-regulated on D7 of embryo implantation. P value˂0.05 is considered significant. SIGNIFICANCE Spatio-temporal expression of ERs in the uterus during peri-implantation period have crucial role for endometrium receptivity and implantation in hamster. Recurrent implantation failure is the devastating problem among the desirable couple and is mainly due to defect in endometrium receptivity. This study may provide a new insight to manage the problem of idiopathic infertility.

Abstract
Blastocyst implantation is an interactive process between the embryo and the uterus. The synchronization of embryonic development with uterine differentiation to a receptive state is essential for a successful pregnancy. The period of uterine receptivity for implantation is limited. Although implantation involves the interaction of numerous signaling molecules, our understanding of the hierarchical mechanisms that coordinate with the embryo-uterine dialogue is not yet sufficient to prevent infertility caused by implantation failure. This review highlights our knowledge on uterine receptivity and hormonal regulation of blastocyst implantation in mice. We also discuss the adhesion molecules, cross-linker proteins, extracellular proteins, and matricellular proteins involved in blastocyst implantation. Furthermore, our recent study reveals that selective proteolysis in an activated blastocyst is associated with the completion of blastocyst implantation after embryo transfer. A better understanding of uterine and blastocyst biology during the peri-implantation period would facilitate further development of reproductive technology.
