Project description:Embryo implantation into maternal endometrium is critical for initiation and establishment of pregnancy, requiring developmental synchrony between endometrium and blastocyst. However, factors regulating human endometrial-embryo cross talk and facilitate implantation remain largely unknown. Extracellular vesicles (EVs) are emerging as important mediators of this process. Here, human trophectomderm stem cell-derived EVs were shown to transfer to and regulate human endometrial cells towards processes associated with implantation. Importantly, transfer of trophectoderm EV cargo proteins to endometrial cells to mediate changes in polarity is demonstrated.

Project description:The aberrant gene expression in the uterine endometrium and embryo has been the major causes of pregnancy failure in cattle. Therefore, selecting cows having adequate endometrial receptivity and embryos of better developmental competence based on the gene expression could increase the number of calves produced by in each cow during its productive life time. We used endometrial and embryo biopsy technology in conjunction with the pregnancy outcome information to establish a direct link between the pre-transfer endometrial or in vivo derived embryo gene expression and pregnancy outcome after embryo transfer. Endometrial samples were collected from Simmental heifers at day 7 and 14 of the estrous cycle, one cycle prior to embryo transfer. In the next cycle, embryo biopsies consisting of 60-70% of inner cell mass and trophectoderm were transferred to the recipients at day 7 of the estrous cycle. The remaining 30-40% parts of the embryos were retained for analysis.Pregnancy diagnosis was performed at days 28 and 42 by ultrasonography and at day 56 by rectal palpation. Those heifers returned to heat at day 21 were considered as non pregnant or non receptive endometrium (NP) while those heifers ended up with successful pregnancy and calf delivery was considered as the calf delivery group or receptive endometrium (CD). Following this, the endometrial samples collected during the pre-transfer period and the embryo biopsies retained during embryo transfer were categorized based on the pregnancy outcome. Those endometrial biopsies collected at days 7 and 14 of the estrous cycle from heifers resulted in successful calf delivery were designated as CDd7 and CDd14, respectively and endometrial biopsies taken at days 7 and 14 of the estrous cycle from those subsequently resulted in no pregnancy were designated as NPd7 and NPd14, respectively. Similarly, the embryo biopsies were classified as those embryo biopsies resulted in successful calf delivery and those resulted in no pregnancy

Project description:Endometrial receptivity plays a vital role in the success of embryo implantation. However, the temporal proteomic profile of porcine endometrium during embryo implantation is still unclear. In this study, the expression of proteins in endometrium on days 9, 10, 11, 12, 13, 14, 15 and 18 of pregnancy (D9, 10, 11, 12, 13, 14, 15 and 18) was profiled via iTRAQ technology. The results showed that 25, 55, 103, 91, 100, 120, 149 proteins were up-regulated, and 24, 70, 169, 159, 164, 161, 198 proteins were down-regulated in porcine endometrium on D10, 11, 12, 13, 14, 15 and 18 compared with that on D9, respectively. Among these differentially expressed (DE) proteins, MQM results indicated that S100A9, S100A12, HRG and IFI6 were differentially expressed in endometrial tissues during embryo implantation period. Bioinformatics analysis showed that the proteins differentially expressed in the 8 comparisons (D10 vs D9, D11 vs D9, D12 vs D9, D13 vs D9, D14 vs D9, D15 vs D9 and D18 vs D9) were involved in important processes and pathways related to immunization, endometrial remodeling, which have a vital effect on embryonic implantation. Our results reveal that RBP4 could regulate the cell proliferation, migration and apoptosis of endometrial epithelial cells and endometrial stromal cells to affect embryo implantation. This research also provides resources for studies of proteins in endometrium during early pregnancy.
